Abstract

A piezoelectric resonating element includes a piezoelectric substrate having a rectangular vibrating portion and a thick-walled portion, excitation electrodes and, and lead electrodes. The thick-walled portion includes a fourth thick-walled portion, a third thick-walled portion, a first thick-walled portion, and a second thick-walled portion. The third thick-walled portion includes a third slope portion and a third thick-walled body, and at least one slit is formed in the third thick-walled portion.
