PROBLEM TO BE SOLVED: To provide a communication apparatus capable of acquiring absolute value of received power accurately and even corresponding to a PHS of next generation, and to provide a received power-measuring method. SOLUTION: The apparatus has: a filter 12 which performs a filter processing to a digitized received signal outputted from an ADC 11; a GI removing portion 13 which removes a guard interval from the filtered received signal, outputted from the filter 12; an FFT portion 14 which applies a high-speed Fourier transform to a received signal which has removed the GI; a sub-channel received power-measuring portion 15 which measures a sub-channel received power to be the absolute value of the received power per sub-channel based on the received signal after an FFT processing and slot received power not through the FFT processing; and an ADC 16 which receives the slot received power RSSI, converts the same into a digital signal and gives the digital signal to the sub-channel received power-measuring portion 15.
