Patent ID: 8558435

Claim:
A piezoelectric device in which a piezoelectric vibration element is mounted in a package wherein said piezoelectric vibration element comprises: two stick-like vibration legs; a central leg provided between said two vibration legs; a coupling portion that couples one end of each of said two vibration legs and one end of said central leg; and a protrusion portion that is coupled to another end of said central leg, has a predetermined angle to the length direction of the central leg, and extends into a direction not interfering with said vibration legs, said predetermined angle excluding 0 degree and 180 degrees wherein said piezoelectric vibration element is supported and fixed in said package at a support point on said central leg and is electrically conducted to external connection terminals, provided on the side of said package, via two conducting points on said protrusion portion, and said piezoelectric vibration element is supported and fixed in said package by at least two support points with one support point on said central leg and at least one support point on said protrusion portion.
