In a mobile phone of the present invention, de-spread circuits execute de-spread processing for receiving signals, and rake combines compose a plurality of information in the outputs of the de-spread circuits in correspondence to base stations, and calculate receiving levels of power control signals in individual channels in correspondence to the base stations to output the power control signals each having receiving level information to a comparator. The comparator outputs only the power control signal having the receiving level lying within a predetermined range from a maximum receiving level of the receiving levels of the power control signals from among the plurality of base stations to a decision circuit. The decision circuit decides based on the power control signal from the comparator whether a transmission power from the mobile phone should be increased or decreased to control the transmission power of a transmitter circuit, thereby preventing misrecognition of the power control signal.
