Abstract

A quartz crystal resonator is provided that includes a body portion with first and second main surfaces facing each other and, in plan view has a pair of long sides extending in a first direction and a pair of short sides extending in a second intersecting direction. Moreover, first and second excitation electrodes are disposed on the first and second main surfaces respectively; a frame surrounds the body portion at both ends and is separated from the both ends; and first and second coupling portions extend from the short sides in the first direction with widths of the short sides. At least one of the first and second coupling portions has a portion whose thickness in a third direction is smaller than a thickness in the third direction of a region of the body portion where the first excitation electrode and the second excitation electrode face each other.
