The present invention is to improve a laminate- molding method and a laminate-molding apparatus for manufacturing molded products that have an external appearance of excellent quality. For this purpose, according to a molding method, by which a mold clamping device (3) laminates skin material (Mm) and a core resin (200), the tension of the skin material Mm, which is inserted into a cavity (9) between a clamped fixed metal mold (11) and a clamped movable metal mold (12) and is laminated by the movable metal mold (12), is varied continuously or in a stepped manner in consonance with the insertion amount of the skin material (Mm). The laminate-molding apparatus comprises a skin material holding device (40) that is attached to the mold clamping device (3), a detector (31) that detects a stroke or a time at the time of clamping the movable metal mold (21), and a skin material holding controller (50) that, upon the receipt of a detection signal, outputs to the skin material holding device (40) a command for altering the tension of the skin material.
