Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent a resin in the vicinity of a gate from sticking to a molding removed from a molding mold when a molding is formed. SOLUTION: A molding mold is equipped with a pair of molds 20, 21 which forms a cavity part 10a corresponding to the form of a molding, a runner part 26 through which a molten resin passes to be supplied to the cavity part 10a, and a gate part 24 which contacts the cavity part 10a and the runner part 26 and sends the resin from the runner part 26 to the cavity part 10a. The surface 25 of the mold constituting the runner part 26 in the vicinity of the gate part is roughened.
