1. A communication apparatus comprising:
a reception circuit that receives a signal transmitted by load-modulating in a communication device, which is a partner in short-range wireless communication, via an antenna, wherein the reception circuit measures a modulation degree of the signal; and
a transmission power control unit that controls transmission power to be transmitted to the communication device on a basis of a reception signal modulation degree, which is the modulation degree of the signal.
