PROBLEM TO BE SOLVED: To provide a mold for molding by which a light guiding body which is a resin molded body with a pattern of fine unevenness on the surface can be molded by injection molding. SOLUTION: A heat insulating barrier 21 consisting of a high-temperature resin is formed on the surface of a main mold 10 made of a metal and a fine unevenness is formed by giving a roughening treatment on the surface and a photosensitive high-temperature layer 31 is formed on the heat insulating barrier 22 with the fine unevenness and a resin pattern layer 32 is formed by patterning and the pattern of the fine unevenness is formed in regions which are not covered with the resin pattern layer 32. |
