PROBLEM TO BE SOLVED: To provide a method for easily and stably producing an artificial marble waterproof pan having light weight convenient for transportation, high strength and luxury appearance. SOLUTION: The artificial marble waterproof pan has a rib on the reverse face of the bottom and is formed by press forming. The rib is integrally formed with a reinforcing material composed of a continuous fiber string, and the reinforcing material is produced by impregnating a reinforcing fiber material with a radically curable molding material containing (A) a thermosetting resin having hydroxy group and ethylenic unsaturated double bond in the molecule, (B) a polymerizable unsaturated monomer and (C) a polyisocyanate.
