Abstract
An artificial marble sheet is formed of a pair of carrier films, an SMC layer and a resin concrete layer which has plasticity but does not contain glass fibers laminated between the carrier films. A method of manufacturing the artificial marble sheet as defined above which includes forming a resin concrete layer which has plasticity but does not contain glass fiber on a first carrier film, forming an SMC layer on a second carrier film and bringing the resin concrete layer and the SMC layer into an intimate contact to each other. Carrier films are removed from the artificial marble sheet and press molding is applied under heating such that the resin concrete layer is located on the side of the surface of the product.
