    摘要： An NFC device according to the present invention includes the following units. An antenna unit (101) receives radio waves from a reader/writer (20) by NFC. A first power source unit (102) generates power from the radio waves. A second power source unit (104) is a drive power source. A power-supply state holding unit (107) holds information indicating a power-supply state of the second power source unit (104). An NFC unit (606) performs NFC via the antenna unit (101) to transmit the information indicating the power-supply state of the second power source unit (104). A power source switch unit (103) switches the second power source unit (104) to the first power source unit (102) according to the power-supply state of the second power source unit (104), in order to supply power to activate at least the NFC unit (606) and the power-supply state holding unit (107). Here, the power source switch unit (103) switches the second power source unit (104) to the first power source unit (102), when the information indicates that the second power source unit (104) is powered OFF.
