Abstract:
A method for producing a vibration gyro sensor, comprising the steps of:stacking and integrating at least a substrate layer and a thin plate layer composed of green sheets, followed by firing to produce a fired product including, in an integrated manner, at least one or more vibrators each having a major axis extending in a certain direction, a support base extending in a direction perpendicular to said certain direction, for supporting said vibrator at one end, a frame having its frame surface parallel to a plane which includes said certain direction and said extending direction of said support base, for surrounding said vibrator and said support base, and at least one or more detecting sections attached between said support base and said frame;forming at least one or more piezoelectric/electrostrictive elements on at least said detecting sections in accordance with a film formation method;adjusting a resonance frequency for driving by applying a trimming treatment to a part of said vibrator; andadjusting a resonance frequency for detection by applying a trimming treatment to a part of said support base.
