Abstract
The crystal element includes: a mesa-shaped crystal piece in a substantially rectangular shape in a plan view including an oscillation section having a first protruded section and a second protruded section; excitation electrodes provided on both main surfaces of the oscillation section; leading sections provided side by side along a prescribed side of the crystal piece; and a wiring section connecting between the excitation electrodes and the leading sections. The first protruded section and the second protruded section include sloping side faces. The side face of the first protruded section located on the +X-side overlaps with the side face of the second protruded section located on the +X side, and the side face of the first protruded section located on the −X-side overlaps with the side face of the second protruded section located on the −X side.
