PURPOSE:To simplify greatly the set assembly by providing a local oscillator and an IC on a straight line for a monolithic structure of a tuner device together with addition of a shielding plate. CONSTITUTION:The detection signals are obtained easily from local oscillators 15V and 15U just by providing a lead wire over these oscillators since both oscillators 15V and 15U just by providing a lead wire over these oscillators since both oscillators 15V and 15U and an IC21 are distributed approximately on a straight line. In addition, the mutual interference is not produced between a tuner part and a channel selection part because said lead wire is not drawn around. As this tuner device has a monolithic structure, the overall size and weight of the tuner device can be reduced. Furthermore the set assembling processes are simplified and decreased. Then a shielding plate 17 is added together with a high frequency input terminal 1a and an intermediate frequency output terminal 1b set at the tuner side. While a digital signal terminal 2a is provided at the channel selection side. As a result, the mutual interference can be reduced less between circuits.
