摘要

PROBLEM TO BE SOLVED: To provide a method of forming a film capable of suppressing variation in the film thickness when forming a film by applying a coating liquid, and to provide a method of manufacturing an electromechanical conversion element, an electromechanical conversion element manufactured by the manufacturing method, a droplet ejection head and a droplet ejection device, and a droplet ejection head and a droplet ejection device for use in the manufacturing method.SOLUTION: In the way of repetition of film formation process, the thickness of a film is measured, and the coating conditions of coating liquid in the remaining process for forming a film are changed based on the measurement results of the thickness of a film. When performing the remaining process for forming a film, coating of the coating liquid is controlled based on the coating conditions thus changed.
