Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method of a micron-sized gear-shaped resin molded product which can manufacture a gear further finer than a conventional fine gear at low cost and in large quantities.SOLUTION: In a manufacturing method of a micron-sized gear-shaped resin molded product, a complex fiber has a circular complex cross section composed of a slightly-soluble polymer (a) and an easily-soluble polymer (b), the slightly-soluble polymer (a) has a shape having, at the circular complex cross section, three or more of round cross sections and protrusions extending from centers of the round cross sections and having the same heights of the round cross sections at equal intervals on circumferences of the round cross sections, the easily-soluble polymer (b) spins the complex fiber which is arranged so as to fill recesses formed between and among the protrusions, and the easily-soluble polymer (b) is melted and removed after cutting the complex fiber in a fiber axial direction, or cut in the fiber axial direction after melting and removing the easily-soluble player (b) from the complex fiber.
