摘要： Provided is a laminated member for a novel automobile interior ceiling material which has good film formability, lightweight and high rigidity, excellent moldability on cold-pressing after preheating, no problem of wrinkles, improved shrinkage and heat resistance of a post-molding product (automobile interior ceiling material), and a small post-molding dimensional error. A laminated member (A) has a seven-layered structure including filler-containing polypropylene sheets (4 and 5) laminated on both sides of a foamed polyurethane sheet (1) with hot melt materials (adhesive layers) (2 and 3) interposed therebetween, and an adhesive layer (6) laminated to adhere an interior material (8) to an outer surface of one-sided filler-containing polypropylene sheet (4) and a backing material (7) adhered to an outer surface of the other-sided filler-containing polypropylene sheet (5).
