Abstract
A package structure for a piezoelectric resonator includes a base which has a shape of flat box and made of an insulating material, and a thin lid bonded to the upper side of the base. A tuning fork type quartz crystal resonator piece is mounted at its one end, that is its base end, on electrode pads provided on the mounting surface in a cantilever manner using conductive adhesive so that it is parallel to the mounting surface, and hermetically sealed in a package with the lid engaged therewith. Either one or both of the mounting surface of the base and the inner surface of the lid has a recess formed at the location adjacent to the free end of a tuning fork type quartz crystal resonator piece so that the free end does not touch the inside surfaces of the packages when the quartz crystal resonator piece is largely dislocated on external impact.
