VIBRATION PIECE, VIBRATOR, OSCILLATOR, AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a vibration piece which achieves excellent strength of joining to an object (particularly, a base substrate of a package) while inhibiting spreading of an adhesive, and to provide a vibrator including the vibration piece, an oscillator, and an electronic apparatus.SOLUTION: A vibration piece 200 includes: a base part 220; at least a pair of vibration arms 230, 240 which protrudes from the base part 220; a support arm 250 which protrudes from the base part 220; and a first through hole 251 which is formed at the support arm 250 and penetrates through the support arm 250 in a thickness direction. The vibration piece 200 is fixed to an object through an adhesive intruding into the first through hole 251.
