description	An angular velocity detection apparatus includes an angular velocity detection signal amplifier circuit which amplifies an angular velocity detection signal Vo output from an angular velocity sensor, and an offset control circuit which controls an offset so as to be a reference voltage which is output when a value of an angular velocity is 0. The angular velocity detection apparatus further includes an input switch circuit which selects the reference voltage and a discharge switch circuit which short-circuits a capacitor included in a high-pass filter in an offset control period.
