Abstract
A vibrating gyroscopic sensor element including a cantilever vibrator, at least one first depression on the cantilever vibrator, a pair of detection electrodes provided on the cantilever vibrator and at least one second depression on the cantilever vibrator. The cantilever vibrator projects from a base area of the vibrating gyroscopic sensor element and the first depression is effective to adjust the frequency difference between a vertical resonance frequency and a horizontal resonance frequency of the vibrator. Further, the second depression is effective to adjust the difference of signals output from the detection electrodes.
