Abstract

A RFID tag includes an inlet in which an antenna for communication and a circuit chip performing radio communication with the antenna are electrically connected to each other. The RFID tag further includes a thermal storage section which encloses the inlet, which is made of a nonmetal, and which prevents thermal diffusion into the inlet and a thermal insulating section which encloses the thermal storage section, which prevents thermal conduction to the thermal storage section, and which has higher thermal diffusivity than thermal diffusivity of the thermal storage section and lower thermal conductivity than thermal conductivity of the thermal storage section.

Claims (7)

1. A RFID tag comprising:

an inlet in which an antenna for communication and a circuit chip performing radio communication with the antenna are electrically connected to each other;

a thermal storage section that encloses the inlet, that is made of a nonmetal, and that prevents thermal diffusion into the inlet; and

a thermal insulating section that encloses the thermal storage section, that prevents thermal conduction to the thermal storage section, and that has higher thermal diffusivity than thermal diffusivity of the thermal storage section and lower thermal conductivity than thermal conductivity of the thermal storage section.

2. The RFID tag according to claim 1 , further comprising:

a case that is made of a nonmetal, and that houses the thermal storage section enclosing the inlet,

wherein the thermal insulating section covers a surface of the case.
