1. A producing method of a photoelectric conversion film, comprising:
forming a photoelectric conversion film containing perovskite crystal particles on a film forming object by causing a photoelectric conversion material dispersion liquid to adhere on the film forming object and pressurizing the photoelectric conversion film to perform a packing process in a film thickness direction and obtain the photoelectric conversion film having a thickness of 10 nm or more and 1000 nm or less,
wherein the photoelectric conversion material dispersion liquid contains: perovskite materials which exist as crystal particles, and have a composition represented by a composition formula: ABX3, wherein A is a monovalent cation of an amine compound, B is a divalent cation of a metal element, and X is a monovalent anion of a halogen element, and have an average particle diameter of 10 nm or more and 300 nm or less; and a dispersion medium which is composed of a poor solvent to the perovskite materials, and in which the crystal particles of the perovskite materials are dispersed in the poor solvent and are not dissolved in the poor solvent.
