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.
