Abstract

Providing a piezoelectric vibrating reed which has low disconnection possibility and ensures reliability for stable operation without requiring strict exposure position accuracy. A piezoelectric vibrating reed 1 including: a piezoelectric plate which includes vibrating arms 3 and 4, a base portion 5 to which base ends of vibrating arms are integrally fixed, and groove portions 6 which are formed on principal surfaces of vibrating arms; and excitation electrodes 10 and 11 to which vibrating arms are vibrate, wherein the excitation electrodes each include: a principal electrode portion 20, a side electrode portion 21 and a connection electrode portion 22, wherein the principal electrode portions are formed such that a horizontal width W1 on the base end sides of the vibrating arms is smaller than a horizontal width W2 in other portions so that a vacant area S is secured on a portion of the principal surface of each of the vibrating arms in the vicinity of a fork portion 15, and wherein the connection electrode portion is formed to have a large width on the principal surface of each of the vibrating arms so as to come close to an opening end side of each of the groove portions by occupying the vacant area.

Description

technical field [0001] The present invention relates to a piezoelectric vibrating piece made of a piezoelectric material such as crystal or lithium tantalate, a piezoelectric vibrator having the piezoelectric vibrating piece, an oscillator having the piezoelectric vibrator, electronic equipment, a radio clock, and a piezoelectric vibrator. A method for manufacturing an electro-vibration piece. Background technique [0002] In recent years, piezoelectric vibrators using crystals or the like as a time source, a timing source of a control signal, a reference signal source, etc. have been used in mobile phones and portable information terminal devices. A variety of such piezoelectric vibrators have been provided, and as one of them, a piezoelectric vibrator having a tuning-fork type piezoelectric vibrating piece is known. The piezoelectric vibrating piece is a vibrating piece that vibrates a pair of vibrating arms arranged in parallel at a predetermined resonance frequency in a...
