Abstract
There is provided a communication apparatus comprising an antenna. A communication unit is able to use external power that is generated by receiving a signal from an external apparatus via the antenna, thereby transmitting a response to the signal that is received from the external apparatus to the external apparatus. A deactivation unit deactivates, in a case where the external power is generated by receiving the signal from the external apparatus via the antenna, supply of the external power from the antenna to the communication unit. A control unit performs control so as to interrupt deactivation of supply of the external power from the antenna to the communication unit by the deactivation unit.
