Abstract

The RFID tag includes a base that can bend and unbend; a communication antenna wired on the base; a circuit chip that is electrically connected to the antenna and performs radio communication via the antenna; a reinforcing member as a chip reinforcing member that covers at least the periphery of the circuit chip and a section of the antenna wiring, the covering preformed at least in an upper side with respect to the base designated as a bottom, and that has a concavo-convex shape and intersects with the antenna wiring at a concave section of the concavo-convex shape; and an adhesive that adheres the reinforcing member to the base, and in which an edge along a concave section of the edge of the reinforcing member traverses over the antenna.

Claims5

Dependent claims

An RFID tag, comprising:

a base that can bend and unbend;
a first antenna provided on the base;
a circuit chip that is electrically connected to the first antenna and configured to perform radio communication via the first antenna;
and
a chip reinforcing member that covers at least a periphery of the circuit chip and a part of the first antenna, and having an edge including a concave section located between two convex sections in a plane parallel to the base,
wherein the concave section is disposed so as to intersect with the first antenna, and wherein, in use, the RFID tag is bendable along a bend line that meets the convex sections, such that a bending radius of a section of the base in the vicinity of the first antenna is greater than a bending radius of other sections of the base that meet the convex sections.
