Abstract
A crystal resonator includes a crystal element and excitation electrodes. The crystal element includes an α crystal region and a β crystal region that have mutually different positive/negative directions along an X-axis. Each two or more of the α crystal regions and the β crystal regions are alternately formed along a direction perpendicular to the X-axis. The excitation electrodes are formed on both surfaces of the respective α crystal region and β crystal region other than crystal regions positioned at both end portions of a row of the α crystal regions and the β crystal regions.
