An RFID tag includes a sheet-like substrate, an IC chip disposed on a first face of the substrate, a conductive adhesive that is positioned around the IC chip along the first face and fixes the IC chip to the substrate, an antenna pattern formed on a second face, of the substrate, that is opposite to the first face, and a through hole that penetrates the substrate toward the conductive adhesive around the IC chip and electrically connects the antenna pattern with the IC chip.

RFID tag

An RFID tag includes: a flexible, sheet-shaped substrate; an antenna pattern that is formed on the substrate; an IC chip that is mounted on the substrate and that is connected to the antenna pattern; an adhesive member that adheres the IC chip to the substrate; and a reinforcement member that covers the IC chip and the adhesive, and that is at a position such that a central portion of the reinforcement member is offset along a length direction of the substrate with respect to the IC chip and the adhesive member.

A disclosed RFID tag includes: a base member; a semiconductor chip mounted on the base member; and an island-shaped reinforcing member covering the semiconductor chip and being configured to reinforce the base member. The reinforcing member has a side portion to which a recess is provided. The recess serves as an originating point of a fold line such that the fold line is formed away from the semiconductor chip when the reinforcing member is folded.

An RFID tag includes a first flexible sheet covering a surface of a base part, an antenna and an IC chip; a second flexible sheet covering an another surface of the base part; a first reinforcing member including third and fourth sheets and covering the chip and a connecting portion of the chip and the antenna, the third sheet having flexibility and elasticity and being disposed on the first sheet, the fourth sheet having flexibility and being disposed on the third sheet; a second reinforcing member including fifth and sixth sheets and covering the chip and the connecting portion, the fifth sheet having flexibility and elasticity and being disposed on the second sheet, the sixth sheet having flexibility and being disposed on the fifth sheet; and an outer member having flexibility and elasticity and covering the first and the second sheets and the first and the second reinforcing members.

An RFID tag is disclosed that includes a first sheet having flexibility and elasticity; an antenna having flexibility and elasticity and configured to be formed on a surface of the first sheet; an IC chip configured to be electrically connected to the antenna; a second sheet having flexibility and elasticity and configured to be attached to the first sheet and to cover the antenna and the IC chip with the first sheet; and a reinforcing member having flexibility and elasticity and configured to cover the IC chip and a connecting portion of the IC chip and the antenna.

A radio tag is disclosed that includes an inlet having a base member, an antenna pattern, and a circuit chip for performing radio communications, the antenna pattern and the circuit chip being provided in the base member and includes a spacer on which the inlet is provided. The spacer has a length in a longitudinal direction thereof twice or more as great as a length of the inlet in the longitudinal direction. The spacer has a flection part at which the spacer is foldable in such a manner as to form an attached surface to be attached to an attached subject of the radio tag.
