There is provided an oscillator circuit including: a current source; a resonant unit; an oscillation amplification unit connected to the current source while being connected in parallel to the resonant unit; a feedback resistor connected in parallel to the oscillation amplification unit; a bypass resistor having a resistance lower than a resistance of the feedback resistor; a switch unit connected between the feedback resistor and the bypass resistor, and configured to switch to the feedback resistor or the bypass resistor; and a control unit configured to control the switch unit such that a current from the current source is bypassed to the bypass resistor during a predetermined oscillation starting period, and to control the switch unit such that the current from the current source flows to the feedback resistor after the predetermined oscillation starting period has ended.
