PROBLEM TO BE SOLVED: To certainly leave a molded product only in a desired mold at the time of mold opening and to enhance reliability and production efficiency. SOLUTION: A holding part 10 is provided to the molding surface 4 of a lower mold 2. The holding part 10 is provided, for example, to the inclined part 4a of the molding surface 4 of the lower mold 2 in a lightly depressed state as the so-called local undercut part, for example by damaging the inclined part 4a by a tool or the like. When an upper mold 3 is raised after molding to open a mold, a part of a resin is bitten in the holding part 10 to lock the surface part of the molded product S to hold the molded product S in the lower mold 2. The holding part 10 may have a size for holding the molded product on the molding surface 4 of the lower mold 2 and may be depressed, for example, at a depth of 1 mm or below.
