PROBLEM TO BE SOLVED: To prevent the deterioration in the appearance of a laminated molding caused by the separation of a skin material from a core material when a clearance is formed between the skin material and a mold cavity surface from a state that the skin material and the core material are integrated in order to make the skin material damaged by being loaded with a high voltage during injection packing self-recover by elastic force. SOLUTION: A gas passage in which one end is connected to an air supply line and the other end is opened to the mold cavity surface is formed in a landed mold which holds the skin material by a pair of male and female shear edge parts. A movable mold is opened slightly in prescribed timing within a cooling time to form a clearance between the skin material and the mold cavity surface, simultaneously gas is introduced into the clearance through the gas passage, and the gas is sealed by the entire circumferences of the shear edge parts to hold a prescribed pressure. Since the skin material is being pressed to the side of the core material, the separation of the skin material from the core material during mold opening can be prevented.
