1. A method of producing fine particles of metal complex pigment, comprising the step of:
reacting a solution of an alkali metal salt of a ligand that constitutes the metal complex with a solution of salts of a metal that constitutes the metal complex, in a liquid flow course of a laminar flow in a channel filled with a fluid.
