PURPOSE:To enable compensation of various drifts of an angle detector with a differential amplifier, by extracting a difference between angular velocity detection bodies of the same construction while only one of the two bodies is provided with an angular velocity detecting capacity. CONSTITUTION:An angular velocity detector 1 supplies an output of a gyroscope body 12 utilizing a tune fork type gyroscope to a differential amplifier 3 as voltage giving an angular velocity through a bearing detection element 13. On the other hand, an output of a drift detector 2 with the angular velocity detector 1 from which the gyroscope body 12 as angular velocity detecting function part is removed is also supplied to the differential amplifier 3. The drift detector 2 outputs various drifts and the differential amplifier 3 outputs an angular velocity voltage with various drifts almost compensated for to make an angular velocity output with an integrator 4.
