CONSTITUTION: A resin particle body comprising synthetic resin and organic filler is added' to the mixed liquid comprising polymerized unsaturated compound and inorganic powder at the weight ratio of 100:100-250. The specific gravity of the resin particle body is smaller than the specific gravity of the mixed liquid by 0.1 or more, and the particle diameter of the resin particle body is 0.5-3.5mm. The weight ratio of the mixed liquid and the resin particle body becomes 100:0.5-10. The polymerized composition formed in this way is injected into a mold. After the resin particle body is deviated in the surface layer part, polymerization is performed. This is the manufacturing method of molded products having these characteristics and the mottled pattern.
