満足しない場合が多かった。[0003] Although such a high-voltage cable is exposed to high heat near an internal combustion engine, it is easily deteriorated by heat and has a problem in reliability. Further, since the water repellency at the time of being wet is poor, the ignition energy loss is increased. Further, accessories such as connectors are connected to or attached to the high-voltage cable, and these accessories are often made of silicone rubber when heat resistance is required. However, the conventional high-voltage cable as shown in FIG. 2 has a weak adhesive force and often does not satisfy reliability or waterproofness.
