PROBLEM TO BE SOLVED: To provide a broadcast receiver capable of accurately detecting an interference wave level and effectively reducing the influence of the interference wave even when a deviation occurs in a center frequency of an input modulation signal. SOLUTION: An interference wave level detecting means detects an adjacent interference wave level with the input modulation signal as an input and on the basis of outputs of one or a plurality of second bandpass filters for making the interference wave pass. The center frequency of passbands of the second bandpass filters is controlled in accordance with the center frequency of the input modulation signal detected by a center frequency detecting means.
