ABSTRACT:
Crystal devices are disclosed that include a crystal frame having a crystal vibrating piece and an outer frame. The crystal vibrating piece includes excitation electrodes, and the outer frame supports the crystal vibrating piece. Each device has a base including connection electrodes on a first surface thereof and respective external electrodes on a second surface thereof, wherein the connection electrodes are electrically connected via respective through-holes to respective excitation electrodes and to respective external electrodes. The first surface of the base is bonded to the under-surface of the outer frame, and an upper surface of the outer frame is bonded to a crystal lid. The through-holes have non-circular transverse profiles and are filled with a sealing material such as a metal.
