摘要： There is provided a light reflection plate that can uniformly exhibit high light diffusibility. The light reflection plate includes 100 parts by weight of a polyolefin-based resin and 20 to 120 parts by weight of a coated titanium oxide that is obtained by coating a surface of titanium oxide with a coating layer containing aluminum oxide and silicon oxide. The coated titanium oxide is constituted by primary particles having a particle size of 0.10 to 0.39 μm and agglomerated particles which are formed by agglomeration of the primary particles and have a particle size of 0.4 μm or more. The number of the agglomerated particles in a cross section of the light reflection plate in a thickness direction is 0.1 to 4.5 /900 μm2 and the number of the primary particles, which are not agglomerated, in the cross section of the light reflection plate in the thickness direction is 1.5 to 11.0 /900 μm2.
