摘要： To provide a voltage controlled oscillator capable of being treated as a lumped constant circuit, having small size and capable of obtaining an oscillation frequency in a high frequency band. A resonance part 1 in a voltage controlled oscillator has variable capacitance elements 13, 14 whose electrostatic capacitance varies in accordance with a control voltage for frequency control input from the outside and an inductance element 11, an amplifying part 21 amplifies a frequency signal from the resonance part 1, and a feedback part 2, having feedback capacitance elements 22, 23, forms an oscillation loop together with the amplifying part 21 and the resonance part 1 by making the frequency signal amplified in the amplifying part 21 to be fed back to the resonance part 1. Further, the resonance part 1 and the feedback part 2 are provided on a quartz-crystal substrate 5.
