ABSTRACT:
A packaged piezoelectric oscillator is provided which comprises an insulating package body, a piezoelectric element, and a lid member. The package body has an upwardly open housing groove which has a bottom surface formed with oscillator electrodes at both ends of the housing groove. The piezoelectric element is fixedly received in the housing groove of the insulating package body and held in electrical conduction with the respective oscillator electrodes. The lid member is attached to the package body to close the housing groove. The housing groove has an intermediate wider width portion, and each end of the housing groove is provided with a pair of end positioning walls projecting toward each other for providing a narrower width portion between the pair of end positioning walls.
