Abstract: PROBLEM TO BE SOLVED: To provide an angular velocity sensor of high accuracy with reduced detection errors. SOLUTION: First and second drive vibrators 16, 17 are arranged almost symmetric with respect to a point O on an x-y plane. A detection vibrator 12 is formed in frame shape almost symmetrical, with respect to the point O to surround the drive vibrators 16, 17. The drive vibrators 16, 17 are supported floatingly to the detecting vibrator 12 via first driving springs 41, 42 and second drive springs 46, 47 almost symmetric with respect to a y- direction passing the point O, so as to be able to vibrate in an x-direction. The detection vibrator 12 is supported floatingly to a stress relaxing frame 11 (a base) via detecting springs 32-34 so as to be able to torsionally rotate and vibrate around a z-axis passing the point O. The drive vibrators 16, 17 are coupled via a drive in-phase countermeasure spring 48. Angular velocity is detected by the torsional rotating vibration of the detecting vibrator 12 about the z-axis which passes through the point O in the state of the drive vibrators 16, 17 being driven vibratingly in the x-direction with opposite phase.
