METHOD FOR MANUFACTURING PIEZOELECTRIC ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a piezoelectric element capable of highly precisely forming a piezoelectric element having a flat surface and recessed back face in a simple process. SOLUTION: This method for manufacturing a piezoelectric element comprises a process for preparing a substrate 1 constituted of a porous ferrite, a process for forming a recessed part 1c in the substrate 1, a process for introducing adhesive 3 to a pore 1c of the substrate 1, a process for attaching a surface 2a of a crystal board 2 to the substrate 1 with the adhesive 3, and a process for grinding a back face 2b of the crystal board 2 in a state that the crystal board 2 is attached to the substrate 1.
