るチューナ。In a tuner that receives a desired broadcast frequency by selectively selecting a plurality of tuning circuits corresponding to at least two or more different broadcasting frequency bands, a receiving antenna and the plurality of tuning circuits are connected in parallel. With,
A tuning circuit corresponding to a broadcasting frequency band that does not include the desired broadcasting frequency and a resonant circuit between the above-mentioned receiving antenna is not configured, but only a tuning circuit corresponding to a broadcasting frequency band that includes the desired broadcasting frequency is formed. A tuner comprising means for forming a resonant circuit with the receiving antenna.
