A wireless communication module for engaging in communications with a base station, the wireless communication module being incorporated into an information device having an antenna, includes a transmitter, a transmission power being controlled by the base station; variable impedance matching section arranged between an antenna connector connected to the antenna and the transmitter, which adjusts an impedance by changing a matching parameter for the variable impedance matching section; transmission power detector for detecting the transmission power; and a controller for adjusting the matching parameter based on the detected transmission power of the transmitter detected by the transmission power detector.
