摘要

A method for producing a composite piezoelectric body includes: forming a composite piezoelectric body by filling a non-conductive polymer between a plurality of piezoelectric materials arranged in an array state at predetermined intervals, and polishing one surface of the composite piezoelectric body, from which surface at least the piezoelectric materials and the polymer are exposed, by using an abrasive film in which an abrasive particle is applied to a base film.
