A self-oscillation circuit has a small driving current and can oscillate a stable frequency signal. The self-oscillation circuit includes an oscillating unit (1), configured to self-oscillate; an amplifying unit (3), configured to amplify a frequency signal oscillated at the oscillating unit (1) and feed back the amplified frequency signal to the oscillating unit; and a resonator (5), disposed in an oscillation loop including the oscillating unit (1) and the amplifying unit (3). The resonator (5) has a resonant frequency near an oscillation frequency of the oscillating unit (1) and has a Q-value higher than that of the oscillating unit (1). For example, the Q-value of the resonator (5) is ten times or more the Q-value of the oscillating unit (1).
