PROBLEM TO BE SOLVED: To provide a backside protective sheet for solar batteries which enables the achievement of both of ultraviolet light resistance and a good adhesive force with a backside sealant.SOLUTION: A backside protective sheet for solar batteries comprises: a base material; and a resin layer. The resin layer is produced from a raw material composition including an acrylic polymer and titanium oxide particles. In the resin layer, the titanium oxide particles account for 32-60 mass% to 100 mass% of all of components of the resin layer. 【課題】耐紫外線性と裏面側封止材との良好な接着力とを両立した太陽電池用裏面保護シートを提供する。【解決手段】 基材と樹脂層とを有する太陽電池用裏面保護シートであって、前記樹脂層は、アクリル系ポリマー及び酸化チタン粒子を含む原料組成物から得られ、前記樹脂層中の酸化チタン粒子の含有量は、樹脂層の全成分１００質量％において、３２質量％以上６０質量％以下であることを特徴とする、太陽電池用裏面保護シート。【選択図】なし
