Abstract

A vibrating piece comprises a base and vibrating arms formed protruding from the base, wherein a groove is formed on at least one of the front side and rear side of the vibrating arms, and wherein notches are formed in the base.

Description

[0001] This application is a divisional application of: [0002] Invention name: vibration plate, vibrator, oscillator and electronic equipment [0003] Application date: December 25, 2001 [0004] Application number: 01133844.X technical field [0005] The present invention relates to a vibrating piece made of a crystal or the like, a vibrator equipped with the vibrating piece, an oscillator including the vibrator, and electronic equipment. Background technique [0006] A conventional tuning-fork-shaped crystal vibrating plate as a vibrating plate is provided with a base and two arms protruding from the base, grooves are respectively formed on the surfaces of the two arms. Furthermore, such grooves are similarly formed on the inner side of the arm. The cross-sectional shape of such an arm therefore generally assumes an H-shape. [0007] The characteristics of this substantially H-shaped tuning-fork-shaped crystal resonator are that even if the resonator size is reduced,...
