METHOD OF MANUFACTURING PIEZOELECTRIC ELEMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method capable of enhancing productivity without causing cost increase, by forming an electrode pattern by means other than etching.SOLUTION: The method of manufacturing a piezoelectric element device includes a step for forming an electrode pattern 15 by punching the electrode pattern 15 through a conductive layer for electrode 12 of a laminate 13 having the conductive layer for electrode 12 formed on a plastic film 10, and then removing the part of the conductive layer for electrode 12 other than the electrode pattern 15, and a step for sticking a laminate 17 in which the electrode pattern 15 is formed and a long piezoelectric film.
