ABSTRACT:
A piezoelectric resonator device includes a base holding a piezoelectric resonator element and a lid bonded to the base in order to hermetically seal the piezoelectric resonator element held on the base. In addition, the region of bonding of the base to the lid is composed of at least a nickel-cobalt layer comprising nickel and cobalt, and a metal layer laminated on the nickel-cobalt layer, with the base and lid bonded by heat-melting using a metallic braze material.
