To cancel in-phase components acting on vibrators of first and second sensor units in an angular velocity sensing direction Y, a differential amplification circuit obtains a differential waveform between a first angular velocity sensing waveform J 1 and a second angular velocity waveform J 2. Furthermore, to reduce a residual in-phase component of the obtained differential waveform, input gain adjusting circuits adjust an input gain of the first angular velocity sensing waveform J 1 and an input gain of the second angular velocity sensing waveform J 2 before these waveforms J 1 and J 2 are entered into the differential amplification circuit.
