摘要：
The present invention provides a drive circuit of an oscillation gyro including two piezoelectric elements formed in an oscillator, which includes an adding circuit for supplying a drive signal to one side faces of the two piezoelectric elements and adding signals obtained from the other side faces opposed to the one side faces of the piezoelectric elements, and an oscillation circuit adapted to be fed back with an addition output signal obtained by the adding circuit, wherein a sine wave signal obtained as an oscillation output of the oscillation circuit is supplied to the one side faces of the two piezoelectric elements as the drive signal. Thus, the drive circuit of the oscillation gyro which obtains the stable output with the simple configuration can be provided.
