PROBLEM TO BE SOLVED: To provide a production method for an urethane-based molding having an excellent surface characteristic, in order to solve the problem that, releasability of urethane molding is a problem when having a complicated shape having many irregularities because of having high adhesiveness, and therefore improvement of surface processing technology is required.SOLUTION: A production method for an urethane-based molding has a hardening step in which an urethane-based resin material is supplied into a cavity having a prescribed three-dimensional shape formed of an urethane-based skin, and the urethane-based resin material is hardened.SELECTED DRAWING: None
