PIEZOELECTRIC DEVICE AND METHOD FOR FABRICATING THE SAME

摘要

A surface mount piezoelectric device includes a piezoelectric vibrating piece, a base plate, and a lid plate. The piezoelectric vibrating piece includes a vibrating portion. The base plate has one principal surface that includes a pair of mounting terminals and another principal surface where the piezoelectric vibrating piece is placed. The mounting terminals include a metal film formed by sputtering or vacuum evaporation and electroless plating film formed on a surface of the metal film. The lid plate has one principal surface that includes a metal film and an electroless plating film formed on a surface of the metal film by electroless plating and another principal surface seals the vibrating portion. The electroless plating film formed on the one principal surface of the base plate and the electroless plating film formed on the one principal surface of the lid plate have mutually a same shape and a same area.
