A tuner is provided to correct interference due to multiplexing of an oscillator when selecting a VHF-L(Very High Frequency-Low) band by using a trap unit disposed between an input tune unit and an MOPLL(Mixer Oscillator Phase Locked Loop) circuit. An input tunning unit(21) tunes a high-frequency signal received from an antenna into a first band and a second band. An MOPLL circuit(22) converts the tuned frequency into an intermediate frequency and outputs the intermediate frequency. A trap unit(26) removes a frequency of a predetermined band of the tuned high-frequency signal to output the resultant frequency to the MOPLL circuit when the low band of the first band is selected.
