Abstract

A piezoelectric component includes a support substrate; a piezoelectric element having both ends fixed to the support substrate, so as to be oscillatable; a pair of terminal electrodes located below the ends of the piezoelectric element, respectively; a pair of capacitance-forming electrodes each having a greater width than the piezoelectric element, extending from the pair of terminal electrodes, respectively, toward a center of the piezoelectric element; and excitation electrodes disposed on a first principal surface and a second principal surface of the piezoelectric element, respectively, the excitation electrodes facing each other so that a facing region in which the excitation electrodes overlap with each other as seen in a transparent plan view is defined therebetween, at least part of a region of the pair of capacitance-forming electrodes which protrudes outside the facing region in a width direction thereof as seen in a plan view, being covered with an insulating film.
