Abstract
A thin-film piezoelectric material element includes a piezoelectric part having a laminated structure which a lower electrode film, a piezoelectric material film and an upper electrode film are laminated sequentially, and electrode pads connected with the piezoelectric part. The thin-film piezoelectric material element has solder regulating parts formed on pad surfaces being surfaces of the electrode pads. The solder regulating parts have peripheral edge parts and crossing edge parts connected with the two outer edge parts, and formed to cross the pad surfaces. The crossing edge parts are formed in a bow like curve-shape having curved parts, being gradually distant from the shortest line as they are distant more from the outer edge parts.
