Abstract:
A skin material-coated foamed particle molded body includes a skin material made of a polypropylene-based resin molded body and a polypropylene-based resin foamed particle molded body coated with the skin material. The skin material has a multilayer structure including an inner layer adhered to the foamed particle molded body and an outer layer outside the inner layer. The outer layer contains a polypropylene-based resin and a reinforcement fiber. The inner layer contains the polypropylene-based resin and a reinforcement fiber in a lower content ratio than a content ratio of the reinforcement fiber contained in the outer layer or contains the polypropylene-based resin and substantially no reinforcement fiber. An average value of the outer layer thickness ratio to a sum of the outer and inner layer thicknesses is 0.20 or more and 0.65 or less, and a coefficient of variation Cv of the ratio is 30% or less.
