Abstract

A piezoelectric composite is formed from a piezoelectric precursor prepared by mixing a powder containing piezoelectric material with a binder material and a gap forming material filling a gap formed to the piezoelectric precursor. The gap forming material is then removed from the thus formed piezoelectric composite, thereby forming a piezoelectric element.
