FREQUENCY ADJUSTING METHOD OF PIEZOELECTRIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a piezoelectric frame including a tuning fork type piezoelectric vibrating piece which performs frequency adjustment without working a vibrating arm.

SOLUTION: The piezoelectric frame 21 includes at least a pair of vibrating arms extending from one terminal side of a base part in a first direction. The pair of vibrating arms includes: a tuning fork type piezoelectric vibrating piece having an exciting electrode; a pair of supporting arms extending in the first direction on both outer sides of the vibrating arms; an outer frame part 22 surrounding the tuning fork type piezoelectric vibrating piece; and a connecting part 26 having a predetermined width for connecting the pair of supporting arms and the outer frame part.
