METHOD FOR PRODUCING FILM PATTERN, ELECTROMECHANICAL CONVERSION FILM, ELECTROMECHANICAL TRANSDUCER, LIQUID DISCHARGE HEAD, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a film pattern capable of efficiently producing the film pattern of a functional film in uniform film thickness and shape.SOLUTION: In the embodiment, an expanded pattern area 8 which is a large pattern for covering the whole pattern of a predetermined pattern area 80 (conventional portion of a solution coating pattern) which is a coating pattern of a conventional PZT precursor solution. A film formation area of a patterned PZT precursor film of the embodiment (a portion of a solution coating pattern) is formed by coating the PZT precursor solution so as to be the expanded pattern area 8 including all of the predetermined pattern area 80 which is the conventional portion of a solution coating pattern.
