Patent ID: 7325452

Claim:
A vibrating gyroscopic sensor comprising: a vibrating gyroscopic sensor element; a cantilever vibrator including a piezoelectric film; a driving electrode; a pair of detection electrodes on a first surface of the vibrating gyroscopic element; one or more depressions in the cantilever vibrator effective to adjust the vibration characteristics of the cantilever vibrator; and a support substrate on which the vibrating gyroscopic sensor element is mounted, wherein, the vibrating gyroscopic sensor element is mounted on the support substrate so that a first surface of the cantilever vibrator faces the support substrate, said cantilever vibrator projects from a base area of said vibrating gyroscopic sensor element, and said one or more depressions effective to adjust the vibration characteristics of the cantilever vibrator are provided in an area other than the first surface of the cantilever vibrator, which area is defined as a laser processing region.
