- the shielding layer 4 containing the conductive material is formed in at least a part of the region other than the RFID antenna 3 of the base material 2 constituting the RFID inlay 6, and the laminated structure constituting the RFID label is sufficient. Is not limited to the structure shown in FIGS. 2, 9 and 10.
- FIG. 8 describes how to attach the second RFID label 10B so that the extending direction of the RFID antenna 3 matches the circumferential direction of the test tube P2.
- the second RFID label 10B may be attached so that the extending direction of the RFID antenna 3 matches the axial direction of the test tube P2.
- the RFID label 10, RFID label 20 and RFID label 30 according to the present embodiment may be so-called mountless labels to which the separator S is not temporarily attached.
- a release agent layer is provided on the surface of the label base material 7.
- a release agent layer is provided on the surface of the base material 22 opposite to the surface on which the RFID antenna 3 is formed. This makes the separator S unnecessary.
- the first RFID label 10A may also be the RFID label 10.
- the shielding layer 4 is set to a size capable of covering the RFID inlay 6 of the RFID label 10.
- the adherend is the bag body P1 or the test tube P2 has been described, but the form of the adherend is not limited to these.

Abstract
Description
図1は、本発明の実施形態に係るRFIDラベル10の外観図である。図2は、図1のII-II線における断面図である。
本実施形態に係るRFIDラベル10は、電波を遮蔽する効果を有する遮蔽層4を備える。このため、RFIDラベル10の遮蔽層4が、既に被着体に貼り付けられている別のRFIDラベルのRFIDインレイを覆うように重ねて貼り付けられた場合には、別のRFIDラベルのICチップに記憶された情報を読取装置により読み取ることができなくなる。
続いて、上述したRFIDラベル10の使用方法について説明する。図5から図8は、RFIDラベル10の使用方法を説明する図である。
<第一変形例>
図9は、第一変形例に係るRFIDラベル20の断面図である。
図10は、第二変形例に係るRFIDラベル30の断面図である。
図11は、第三変形例に係るRFIDラベル40の外観図である。
図13は、第四変形例に係るRFIDラベル50の外観図である。
以上、本発明の実施形態について説明したが、上記実施形態は、本発明の適用例の一部を示したに過ぎず、本発明の技術的範囲を上記実施形態の具体的構成に限定する趣旨ではない。
