Abstract

PURPOSE:To simplify a alignment process of mask patterns while maintaining the high performance of vibrators by largely designing mask patterns for electrodes so as to overhang to the outside from the outside contour of the vibrators and positively imparting electrode films spacelessly to the outside contour parts of the vibrators.
