The present invention provides a layered product which has excellent sunlight reflection performance, and can obtain high conversion efficiency when used as back sheets for solar cells, and also has excellent infrared light reflection performance, and low heat storage. The layered product comprises: a layer (A) comprising 0.1-40 parts by mass of titanium oxide particles per 100 parts by mass of a thermoplastic resin in which the titanium oxide particles have a volume average particle diameter of 0.01 µm - 0.35 µm and include particles having a particle diameter of 0.5 µm or more in an amount of less than 10 mass%; and a layer (B) comprising 0.1-40 parts by mass of titanium oxide particles per 100 parts by mass of a thermoplastic resin in which the titanium oxide particles have a volume average particle diameter of 0.5 µm - 2 µm and include particles having a particle diameter of 0.35 µm or less in an amount of less than 10 mass%. The titanium oxide is preferably of a rutile form. The thermoplastic resin of the layer (A) and/or layer (B) preferably comprises an aromatic vinyl resin, a polyester resin or a polyolefin resin. The layer (A) may be layered on the layer (B) directly or via another layer (C). The layer (A) may be arranged on both sides of the layer (B), or the layer (B) may be arranged on both sides of the layer (A). |
