A method of manufacturing piezoelectric vibrators

摘要

A piezoelectric vibrator wafer which includes a plurality of vibrator chips each including a vibrator portion, a frame portion and connecting portions for connection between them, and joint portions for connecting the vibrator chips to each other, with the vibrator chips and joint portions being integrally formed in one unit by a metallic material to constitute the piezoelectric vibrator wafer. The joint portions each have such dimensions as will be readily fused upon passing of electric current through them. Invention by described.
