摘要： There is provided an oscillation type gyro sensor including an oscillation gyro device, an oscillation circuit, a controller, and an impedance conversion circuit. The oscillation gyro device includes a piezoelectric device including a drive electrode and a detection electrode, oscillates according to a drive signal input to the drive electrode, and is capable of generating an output signal including a detection signal corresponding to a Coriolis force from the detection electrode. The oscillation circuit outputs, based on the output signal, a signal for oscillating the oscillation gyro device to the drive electrode as the drive signal. The controller controls the oscillation circuit such that the oscillation circuit outputs a drive signal that makes the output signal constant. To the impedance conversion circuit, the drive signal output from the oscillation circuit is input.
