Abstract:
A method for producing a thin film piezoelectric element, including the steps of:a) forming a first metal electrode film, a first thin film piezoelectric element, and a second metal electrode film on a first substrate in this order; b) forming a third metal electrode film, a second thin film piezoelectric element, and a fourth metal electrode film on a second substrate in this order; c) attaching the second metal electrode film to the fourth metal electrode film; d) removing the first substrate by etching; e) shaping the first metal electrode film, the first thin film piezoelectric element, the second metal electrode film, the fourth metal electrode film, the second thin film piezoelectric element, and the third metal electrode film; f) covering the first metal electrode film, the first thin film piezoelectric element, the second metal electrode film, the fourth metal electrode film, the second thin film piezoelectric element, and the third metal electrode film, with a coating resin; and g) removing the second substrate by etching.
