ABSTRACT:
With a crystal vibrator, a package (housing) is produced by joining a base to a lid, and an internal space is formed within this package. A crystal resonator plate is held on the base in this internal space, and the internal space of the package is sealed airtight. In placing the crystal resonator plate on the base, the +X axial direction of the crystal resonator plate within the internal space is set.
