PROBLEM TO BE SOLVED: To provide a molded product of a polyvinyl chloride resin having light transmission properties and improved flame retardancy. SOLUTION: The molded product of the polyvinyl chloride resin is obtained by mixing 1-20 pts. wt. hydrate compound having 0.05-0.5μm average particle diameter with 100 pts. wt. polyvinyl chloride resin, and melt-molding the mixed product. The hydrate compound having the 0.05-0.5μm average particle diameter provides a molded product having the light transmission properties because the particle diameter is near to the wavelength of a visual light, and does not refract the light considerably, heightens the flame retardancy of the molded product because hydrated water is released at the increased temperature at a fire.
