PROBLEM TO BE SOLVED: To provide a light reflection sheet having excellent light reflectance without using a resin originating from petroleum resources. SOLUTION: The light reflection sheet is formed of a thermoplastic resin material including a polylactic acid resin, titanium oxide, and an inorganic filler other than titanium oxide, wherein the content of titanium oxide is 5-15 mass%, the content of the inorganic filler is 10-30 mass%, with extrusion molding. Consequently, the light reflection sheet is manufactured by using a non-petroleum resin, that is the polylactic acid resin, and moreover, the light reflection sheet has excellent light reflecting characteristics, and sufficient rigidity.
