Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a mold for molding a resin preventing deterioration of the quality of a resin molded article and capable of reducing labor necessary for the finish processing of the resin molded article. SOLUTION: In a mold for molding a resin, a resin material is charged in a cavity 3 through a runner 1 to be cured. The first runner 1 is branched into a plurality of branch runners 2 and these branch runners 2 are connected to one cavity 3. The runner cutting pin inserted in the resin material remaining at the branch point of the branch runners 2 after the cavity 3 is filled with the resin material is provided. Since the cavity 3 is filled with the resin material from a plurality of the branch runners 2, the filling properties of the cavity 3 with the resin material can be enhanced as compared with a case filling the cavity from one place.
