Abstract
A piezoelectric device is provided and includes: a piezoelectric vibrating piece, having an outer shape in rectangular shape and including an excitation electrode formed on both principal surfaces which are a top surface and a lower surface, an electrode pad formed at both ends of one short side, and an extraction electrode extracted from the excitation electrode to the electrode pad to be electrically connected to the electrode pad; a package, including a placement surface on which the piezoelectric vibrating piece is placed as opposed to the lower surface of the piezoelectric vibrating piece, and an adhesion pad formed on the placement surface; and a conductive adhesive, securing the piezoelectric vibrating piece to the package and electrically connecting the adhesion pad to the electrode pad. An adhesive is applied on the top surface of the piezoelectric vibrating piece and between the conductive adhesive and the excitation electrode.
