| 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.
