PRECURSOR SOLUTION, METHOD FOR MANUFACTURING PIEZOELECTRIC ELEMENT, METHOD FOR MANUFACTURING LIQUID INJECTION HEAD, AND METHOD FOR MANUFACTURING LIQUID INJECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a precursor solution and the like, the precursor solution being able to improve in-plane uniformity of piezoelectric characteristics of a piezoelectric layer obtained when it is manufactured by a liquid phase method.

SOLUTION: The precursor solution is used for forming a piezoelectric body. In ligands coordinated to metal included in the precursor solution, 90% or more thereof is the same kind of ligand.
