Abstract:
1. A manufacturing method of a resin molding mold for molding a resin molded body which has a fine structure and at least one of a through-hole and an outer form obtained by a mold pressing structure, comprising: preparing a base die which has a first concave part corresponding to the fine structure and a second concave part corresponding to at least one of the through-hole and the outer form and being deeper than the first concave part; first electroforming with a first material on the base die; second electroforming with a second material different from the first material over the first material electroformed in the first electroforming; and removing the first material electrodeposited on the second concave part to form a protruding part for forming at least one of the through-hole and the outer form, wherein the first material has a smaller electroforming stress than the second material, the first material has a higher adhesiveness with regard to the base die than the second material and the second material is harder than the first material.
