<P>PROBLEM TO BE SOLVED: To provide a light reflecting sheet that is molded inexpensively and easily while ensuring high light reflectance. <P>SOLUTION: The light reflecting sheet is prepared by molding a molding material comprising: a polypropylene resin whose melt flow rate (MFR) at 230°C obtained by measuring the resin according to conditions of ISO 1133 is ≤10; and an inorganic filler according to an extrusion molding. Therein, titanium oxide as the inorganic filler is contained by 4 to 15 mass% per the total amount of molding material, and the inorganic filler other than titanium oxide is contained by 12 to 30 mass% per the total amount of the molding material. <P>COPYRIGHT: (C)2010,JPO&INPIT |
