Abstract

A piezoelectric vibrating piece includes a pair of vibrating arm portions which are arranged with a center axis interposed therebetween, a base portion which is arranged between a pair of vibrating arm portions and fixed to the outside, and a pair of connecting portions which connect proximal end portions of a pair of vibrating arm portions and a proximal end portion of the base portion. The distance between distal end portions of the vibrating arm portions and the center axis is smaller than the distance between the proximal end portions of the vibrating arm portions and the center axis.
