Abstract:
A piezoelectric vibrating piece includes: a pair of vibrating arm sections which are disposed at a distance away from each other in a width direction of a base section; the base section to which each base end of the pair of vibrating arm sections is connected; and a support arm section that is connected to the base section between the pair of vibrating arm sections and extends from the base section to the same side as the pair of vibrating arm sections, in which convex sections are formed continuous with side surfaces of roots of the vibrating arm sections and side surfaces of the base section.
