PROBLEM TO BE SOLVED: To suppress such a phenomenon that glass fibers contained in a molding material come out to cause the surface roughness of the groove bottom part of a mounting groove to become large and irregular while enhancing sealability in a method for producing a resin molded product such as a resin cover or the like by a mold. SOLUTION: In a method for producing a molded product 1 such as a resin cover or the like wherein a lid part is provided to the base end of the cylindrical insert part 2 inserted in the opening part of a partner part and a mounting groove 4 for mounting a packing is provided to the outer peripheral surface of the insert part 2 by a mold by using a glass fiber-containing resin as a molding material, when the molding material is injected in the cavity space of the mold, the molding material is allowed to flow from the injection gate 10 arranged at the leading end position of the insert part 2 in the molded product toward the lid part 3. |
