  • Example 4 was rated B in the electromagnetic wave permeability evaluation.
  • Example 5 had an electromagnetic wave permeability evaluation of B and a disconnection robustness evaluation of A
  • Example 6 had an electromagnetic wave permeability evaluation of S and a disconnection robustness evaluation of B.
  • the narrower the spacing between the plurality of auxiliary wirings in the first direction D1 the more robustness against disconnection
  • the wider the spacing between the plurality of auxiliary wirings in the first direction D1 the more improved the electromagnetic wave permeability. Recognize. From Examples 4 and 5, it can be seen that both the electromagnetic wave permeability and the robustness against disconnection can be satisfactorily achieved regardless of whether the spacing between the plurality of auxiliary wirings is 0.40 mm or 1.6 mm.
  • Example 7 the electromagnetic wave permeability evaluation was S, and the disconnection robustness evaluation was A.
  • the electromagnetic wave transmittance was -0.55 dB, which was superior to the electromagnetic wave transmittance of -0.6 dB in Example 1.
  • the smaller the gap between the dummy wiring and the main wiring the better the electromagnetic wave permeability. Therefore, even when the current-carrying member has a dummy wiring, the electromagnetic wave permeability and robustness against disconnection can be improved. I know you can.
  • Example 9 As in Example 1, the electromagnetic wave permeability evaluation was S and the breakage robustness evaluation was A. As described above, regardless of the shape of the current-carrying member, when a plurality of auxiliary wirings continuously intersect two or more main wirings, it is possible to achieve both electromagnetic wave permeability and robustness against disconnection.
  • Example 11 As in Example 1, the electromagnetic wave permeability evaluation was S and the breakage robustness evaluation was A. As described above, regardless of the manufacturing method of the current-carrying member, when a plurality of auxiliary wirings continuously intersect two or more main wirings, it is possible to achieve both electromagnetic wave permeability and robustness against disconnection.
  • Comparative Example 1 the electromagnetic wave permeability evaluation was S, while the disconnection robustness evaluation was C.
  • Comparative Example 1 there is only the main wiring extending along the first direction D1, and there is no auxiliary wiring. Therefore, if the main wiring is broken, there will be a portion where current cannot flow between the pair of electrode pads. Therefore, it is considered that the disconnection robustness evaluation was C.
  • Comparative Example 3 the wire breakage robustness evaluation was A, while the electromagnetic wave permeability evaluation was C.
  • Comparative Example 3 since the plurality of auxiliary wirings continuously intersect with the 16 main wirings and have a length of 2.40 mm, the electric field oscillates in the direction orthogonal to the first direction D1. It is considered that the electromagnetic wave permeability evaluation was D because the polarized wave and the plurality of auxiliary wirings interfered with each other and shielded the polarized wave.
  • Comparative Example 4 the wire breakage robustness evaluation was A, while the electromagnetic wave permeability evaluation was C.
  • the interval between the plurality of auxiliary wirings in the first direction D1 is as short as 0.25 mm, and one auxiliary wiring is spaced from another auxiliary wiring at an interval of 0.25 mm in the first direction D1.
  • the current tends to flow in the second direction D2. Therefore, it is considered that the polarized wave having an electric field oscillating in the direction perpendicular to the first direction D1 interferes with the plurality of auxiliary wirings, and the polarized wave is shielded, resulting in the evaluation of the electromagnetic wave permeability being D. .
  • Table 1 shows the results of the visibility evaluation for Examples 1-12 and Comparative Examples 1-4.
  • Examples 7 and 8 had a visibility evaluation of A.
  • the conductive member includes dummy wirings arranged at intervals narrower than the intervals of a plurality of auxiliary wirings in the first direction D1 as shown in FIG. 7, and the mesh pattern MP is formed. It is Therefore, it is considered that the distance between the auxiliary wirings, the existence of the auxiliary wirings, and the existence of the main wirings in the first direction D1 and the second direction D2 were not conspicuous by the observer of the current-carrying member.
  • the present invention is basically configured as described above. Although the current-carrying member of the present invention has been described in detail above, the present invention is not limited to the above-described embodiments, and various improvements and modifications may be made without departing from the gist of the present invention.
