A QPSK modulated digital input signal (10b) and an FM modulated analog input (10a) signal are received, and are processed by a high-frequency signal processing circuit (11a-15), a frequency conversion circuit (16), and an intermediate frequency amplifier portion (20) that are shared between the two signals. A received signal is divided into two signals, which are amplified by separate intermediate frequency amplifier circuits (22a,22b). The outputs of these intermediate frequency amplifier circuits (22a,22b) are individually fed to an FM demodulator (301) and to an I/Q converter (401). Inside the chassis of a tuner, the section for housing the circuit block of the FM demodulator (301) and the section for housing the circuit block of the I/Q converter (401) are arranged with the section for housing the circuit block of the intermediate frequency amplifier (20) placed between them, and the individual circuit blocks are shielded from one another by metal shields.
