摘要： [Object] There has been a need for a composite piezoelectric body and a composite piezoelectric element using the composite piezoelectric body which does not cause electrode defects, disconnection, and peeling even if the piezoelectric body is subjected to fine-pitch processing.[Solution] A composite piezoelectric body of the present invention includes a piezoelectric ceramic and an organic polymer material containing air bubbles mixed therein, wherein among surfaces of the piezoelectric ceramic and the organic polymer material on which an electrode is to be formed, an insulating layer is formed on the entire or a portion of the surface of the organic polymer material on which the electrode is to be formed.
