A method for producing a molded product 70 involves the use of a mold 40 including a cavity 44 to which a molding material is supplied and an intercepting member 45 capable of moving back and forth within the cavity 44. The method comprises an interception step for moving the intercepting member 45 into the cavity 44 and an injection step for injecting the molding material into the cavity 44. During the injection step, the intercepting member 45 is used to regulate the flow of the molding member inside the cavity 44 at the initial stage of the injection. The intercepting member is thereafter pulled into the mold 40.
