Tuning fork type piezoelectric resonator element and method for producing a tuning fork type piezoelectric resonator

摘要

A tuning fork type piezoelectric resonator element having a wide operating temperature range and method of manufacture comprising a base having two sides and opposite ends,a plurality of resonating arms 18 protruding from one end of the base 12, a plurality of mount electrodes 16 corresponding in number to said resonating arms disposed at an opposite end of the base 12 and being connected by lead terminals to the mount electrodes using a conductive joining material. The mount electrodes 16 are spaced a minimum distance apart sufficient to prevent shorting caused by diffusion of the conductive joining material 22 for joining lead terminals 32 to the mount electrodes 16 with the lead terminals connected to said mount electrodes without forming a bend in the lead terminals at the end thereof adjacent the mount electrodes and with the width of the base along each side thereof set to a value that permits the lead terminals to be linearly joined to the mount electrodes.
