PROBLEM TO BE SOLVED: To provide a light reflection plate which has excellent heat molding property even if light-reflective fine particles are included, and can be thermally formed into a desired shape.SOLUTION: A light reflection plate includes a polypropylene resin and light-reflective fine particles. In the light reflection plate, the bend elastic constant at 140°C is 5 to 55 MPa. Preferably, the light reflection plate is excellent in heat molding property since crystallization temperature is 110°C or less, and a thermoformed article thermally formed into a desired shape can be manufactured without causing rupture or without ununiformity in thickness. |
