Abstract

PURPOSE:The circumferential portions of the main electrode fromed on a crystal vibrator are removed, whereby the number of operation steps is reduced, whereby the number of operation steps is reduced, the yield is improved, the reduction in costs is achieved and further the degradation in vibration characteristics is prevented.
