Abstract
A method comprises: bonding a plurality of thin film piezoelectric elements, formed on a substrate, onto a temporary fixing substrate via an adhesive layer; selectively removing the substrate to expose the thin film piezoelectric elements; fixing an element housing jig having sectional regions for individually isolating the thin film piezoelectric elements in such manner that the thin film piezoelectric elements and the sectional regions correspond to each other; and dissolving and removing the adhesive layer, and housing the thin film piezoelectric elements in the sectional regions of the element housing jig. Accordingly, it is possible to individually isolate and house the thin film piezoelectric elements removed from the substrate.
