PURPOSE: To make surface wear resistance good as an exterior material by forming a coating layer wherein ceramic particles are densely incorporated under a mutually contacting condition in a resin on a base material of an reinforced plastic.

CONSTITUTION: A base material 2 consisting of a flat reinforced plastic and a mixture wherein a large amt. of specified ceramic 4 particles and resin particles 5 are mixed. The mixture is placed with an approximate uniformity and an appropriate thickness on the surface of the base material 2. A specified coating layer 3 is formed on the base material 2 by melting and curing the resin 5 particles by heating and pressing. Then, by applying bending, cutting etc., to the thus obtd. product, and exterior sheet 1 with a specified shape, for example, an approximately skirt shape. As the coating layer 3 contains a large amt. of ceramic 4, it exhibits a high hardness and therefore, the exterior sheet 1 has a surface which hardly wears and excellent wear resistance.
