THE PRESENT INVENTION PROVIDES A METHOD FOR PRODUCING A MULTILAYERMOLDED ARTICLE COMPRISING A STEP OF SUPPLYING A SKIN MATERIAL HAVING AT LEAST A FOAM LAYER BETWEEN A PAIR OF A MALE MOLD HALF AND A FEMALE MOLD HALF, SUPPLYING A MOLTEN THERMOPLASTIC RESIN BETWEEN THE SKIN MATERIAL AND THE MOLDING SURFACE OF ONE OF THE MALE MOLD HALF AND THE FEMALE MOLD HALF, A STEP OF LAMINATING THE SKIN MATERIAL ONTO AT LEAST A PART OF THE SURFACE OF A SUBSTRATE MADE FROM THE THERMOPLASTIC RESIN AND A STEP OF FORMING A RECESS IN THE SKIN MATERIAL LAMINATING REGION, WHEREIN THE THICKNESS, T (MM), OF THE FOAM LAYER IN THE SKIN MATERIAL BEFORE MOLDING IS 0.6 R OR LESS WHEREIN R REPRESENTS THE MINIMUM RADIUS (MM) OF THE RECESS ON THE SKIN MATERIAL LAMINATING SIDE OF THE SUBSIRATE IN THE SKIN MATERIAL LAMINATING REGION OF THE MULTILAYER MOLDED ARTICLE. THE METHOD OF THE PRESENT INVENTION ALLOWS, WHEN PRODUCING AMULTILAYER MOLDED ARTICLE HAVING A RECESS ON THE SKIN MATERIAL SIDE IN THE SKIN MATERIAL LAMINATING REGION WHILE UTILIZING AN ADVANTAGEOUS PROPERTYPOSSESSED BY AN INJECTION MOLDING AND AN INJECTION PRESS MOLDING WHICH IS THE ABILITY OF LAMINATING A SKIN MATERIAL ONTO THE SURFACE OF THE SUBSTRATE AT THE SAME TIME WITH THE MOLDING OF THE SUBSTRATE, A MULTILAYER MOLDED ARTICLE HAVING NO WRINKLES ON THE SURFACE OF THE SKIN MATERIAL AND HAVING A SATISFACTORY APPEARANCE TO BE OBTAINED EVEN WHEN A SKIN MATERIAL HAVING A FOAM LAYER IS EMPLOYED.
