To provide a member with built-in wireless tag allowing repeated use without using a mechanical switch.
This member with built-in wireless tag incorporates a wireless tag 6 comprising an antenna 3 receiving a radio wave, a wireless tag IC 4 receiving the radio wave to receive power, and transmitting data from the antenna 3 by use of the power, and a switch 5 ON/OFF-controlling the transmission of the data of the wireless tag IC 4. In the switch 5, two terminals 5A, 5B forming a cut position of the antenna 3 are exposed apart from each other on the surface 2a of a member body 2. The switch 5 switches the antenna 3 to a communicable state or incommunicable state by bringing the middle of the terminals 5A, 5B into a conductive state or a cut state.
