PURPOSE: To simplify a production method and to lower a ratio of an unacceptable product in the production of a multilayered molded product comprising a deformable sheet and a thermoplastic or thermosetting resin. CONSTITUTION: In the production of a multilayered molded product of which the rear surface comprises a sheet 6 formed by the injection molding of a resin, the sheet 6 is deformed in a casting mold by a fluid pressure medium, especially, nitrogen of at least 20 bar and, immediately thereafter, the rear surface of the sheet deformed in the casting mold is molded by the injection molding of a resin and, by holding the sheet 6 deformed under pressure to its position during the injection molding of the rear surface, a multilayered molded product is produced. |
