Abstract

A crystal vibrator according to the present invention includes a crystal blank generating thickness shear vibration, a pair of excitation electrodes on both surfaces of the crystal blank, and a pair of extraction electrodes respectively extracted from the excitation electrodes. The crystal blank includes a region provided with a plurality of hill parts which are covered by an excitation electrode. Due to hill parts, it is possible to increase adhesion to the excitation electrodes and to provide a highly reliable crystal vibrator.
