An RFID tag includes an antenna coil configured to transmit and receive a signal through near field communication, a signal processing circuit configured to process the signal transmitted and received by the antenna coil, a capacitive element arranged in series between the antenna coil and the signal processing circuit, and a control unit configured to control the capacity value of the capacitive element. The control unit changes the capacity value of the capacitive element according to whether a voltage is applied from an external power supply.
