Abstract
A piezoelectric device employs solder on a roughened surface to improve bonding of electrical contacts with the device package. The device package includes a base, a crystal frame and a lid. The base includes connecting electrodes on a side of the base adjacent the crystal frame. The base has a through hole and a through hole electrode formed in the through hole in electrical contact with the connecting electrodes. The through hole is sealed with a sealing material and a first external electrode layer, which is electrically connected to the through hole electrode, is formed on an outside surface of the base opposite the piezoelectric plate. A second external electrode layer is formed to cover the first external electrode layer and the sealing material.
