PROBLEM TO BE SOLVED: To provide a VHF band receiver capable of being easily downsized wherein a degree of antenna installation freedom is high. SOLUTION: The FM receiver 100 is provided with: a tuning circuit for selectively passing a tuning frequency and its neighboring frequencies among a received broadcast wave; a local oscillation circuit 13 for generating a local oscillation signal; and a mixer circuit 12 for applying frequency-mixing between the local oscillation signal generated from the local oscillation circuit 13 and a high frequency signal obtained by the tuning operation of the tuning circuit. The tuning circuit comprises an antenna coil 1 wound on a magnetic core and a varactor circuit 2 for configuring a resonance circuit together with the antenna coil 1 and a tuning frequency at VHF bands is set to the tuning circuit.
