An input resonance circuit of a tuner is provided to have a level attenuation unit in a VHF-H input resonance circuit to attenuate a signal level at a VHF-L band of a high frequency signal inputted when tuning a VHF-H band frequency. A first input resonance unit(21) inputs a high frequency signal to the first band. A second input resonance unit(22) inputs a high frequency signal to the second band. A third input resonance unit inputs a high frequency signal to the third band. A level attenuation unit(24) attenuates the level of a second band high frequency signal. The diode is conducted when selecting the second band. |
