The present invention is to provide a noncontact tag, comprising: a clock extraction unit for extracting a clock from a received carrier wave; a demodulation unit for outputting a demodulated signal comprising a logic signal whose logic state changes responding to each of a non-modulation period and modulation period of the carrier wave; a division unit for generating a division clock from the clock input from the clock extraction unit and also restraining the division clock from being output according to a logic state of the demodulated signal; and a decoding unit for decoding information included in the carrier wave by using a value of counter driven by the division clock.
