Abstract
A resonating element has a quartz crystal substrate having a vibrating portion and a thin-walled portion that is thinner than the vibrating portion, and a pair of excitation electrodes respectively disposed on opposite surfaces of the vibrating portion. Moreover, in the excitation electrode, each of a pair of sides arranged in a Z'-axis direction is convexly curved toward the center so that the excitation electrode has a constricted portion in which a length in the Z′-axis direction increases gradually from a central portion toward both ends in an X-axis direction.
