An object is to provide a radio wave receiver capable of enhancing user-friendliness regarding a display of intensity of a received radio wave in a configuration capable of utilizing two different kinds of radio waves. Each radio wave processing portion 1, 2 receives a radio wave, and outputs various kinds of information such as video information (video signal, video data), audio information (audio signal, audio data), and another information (location information, etc.). A switching portion 4 inputs output signals of the first, and second radio wave processing portions 1, 2, selects the output signals according to a switching instruction of a controller 3, and supplies the output signals to a display portion 6 and a speaker 7. In obtaining a power voltage value indicating intensity (intensity of received electrical fields) of received radio waves from each tuner 11, 21, the controller 3 controls a display of the intensity of the received radio waves in both tuners, even if the controller 3 processes the radio wave of one, or both the tuners, and controls a display of the intensity of the received radio waves by switching the intensity of the radio waves received in both tuners based on an operation of an operating portion 5 by a user.
