PURPOSE:To prevent the generation of unevenness on the outer surface of a skin material by laminating the skin material to a specific crosslinked polyolefinic resin foamed body to form a composite material and integrally forming a resin base material layer composed of a mixture of two kinds of specific polyolefinic resins to said composite material on the foamed body side thereof to perform molding. CONSTITUTION:A composite material wherein a skin material 2 is laminated to a foamed body 1 composed of a crosslinked polyolefinic resin having a gel ratio of 20-80% and apparent density of 0.025-0.20g/cc and a resin base material layer 7 composed of a mixture prepared by mixing 2-40wt.% of a low MW polyolefinic resin having an average MW of 2,000-20,000 with a polyolefinic resin having a melt flow rate at 190 deg.C of 1-60g/10min are integrally molded in such a state that said base material layer 7 is arranged on the side of the foamed body 1. As a result, a laminated molded body 8 of high quality characterized by that the resin base material layer 7 easily flows upon the reception of pressure and the reaction force transmitted from the resin base material layer 7 to the outer surface of the skin material 2 can be reduced and the breakage of air bubbles of the foamed body or the generation of unevenness on the outer surface of the skin material 2 is prevented can be obtained. |
