PIEZOELECTRIC VIBRATION PIECE AND PIEZOELECTRIC VIBRATOR

摘要

PROBLEM TO BE SOLVED: To provide a piezoelectric vibration piece which is inhibited from being thermally deformed when heated and mounted on a package, and also to provide a piezoelectric vibrator equipped with such a piezoelectric vibration piece.SOLUTION: A piezoelectric vibration piece includes: a pair of vibration arm parts arranged side by side in the width direction; base parts in which base ends of the pair of vibration arm parts are coupled to each other; a frame-shaped support arm part which extends from the tip side of the vibration arm part from the base part; and a plurality of mount parts which are provided on the tip sides of the vibration arm part than coupling points with the base parts in the support arm part.
