PROBLEM TO BE SOLVED: To economically constitute a broadcast receiver for simultaneously receiving plural broadcasting channels. SOLUTION: Two simultaneously received channel signals are converted into two adjacent frequencies by a high frequency signal converting part 10 and a second high frequency signal converting part 20, so that two intermediate frequency signals can be obtained, and each signal is added by a signal adder/ synthesizer 30. Then, the signal is amplified by an intermediate frequency amplifying part 40, and then demodulated by each corresponding signal demodulating part 50 and 60, and each signal is outputted simultaneously.
