Zusammenfassung:A voltage-controlled oscillator is provided with inductor 7a arranged between a power supply and a ground; and a variable capacitive section 56 that configures a resonator circuit with inductor 7a. Variable capacitive section 56 is provided with first and second control terminals 1, 2 to which a voltage is applied to change the capacitance. Variable capacitive section 56 includes first variable capacitive element 9a wherein one terminal is connected to first control terminal 1 and the other terminal is connected to second control terminal 2; and second variable capacitive element 10a wherein one terminal is connected to second control terminal 2 and the other terminal is connected between the inductor and the ground.
