Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a backside protective sheet which exhibits excellent weather resistance and hydrolysis resistance and therefore, excellent durability even when being used in a solar battery module.SOLUTION: A backside protective sheet for a solar battery module comprises at least a weatherproof layer (A), an insulator layer (B) including a thermoplastic resin, and a sealant adhesion layer (C), which are stacked in this order from outside the backside of a solar battery module. The weatherproof layer (A) has an outer surface which is a layer formed by irradiating an ionizing radiation curable resin composition with ionization radiation to cause crosslinking thereof. The layer formed by the ionizing radiation curable resin composition crosslinked by irradiation with ionization radiation has an elastic modulus of 300-1500 Mpa. The layer formed by the ionizing radiation curable resin composition crosslinked by irradiation with ionization radiation has a breaking ductility of 10-100%.
