Abstract

Provided are a back side protective sheet for a solar cell capable of enhancing adherence to an EVA resin as a filler used to seal solar cell elements and of maintaining a weather resistance over a long period of time; and a solar cell module including the back side protective sheet for a solar cell. The back side protective sheet (10) for a solar cell, which is disposed on a back side of a solar cell module, includes: a first film (11) constituted of a laminated body formed by causing a linear low-density polyethylene layer (111), an interposing resin layer (113), and a linear low-density polyethylene layer (112) to directly contact each other in order; and a second film (12) laminated on the first film (11), with an adhesive layer (13) interposed between the first film (11) and the second film (12). The interposing resin layer (113) is formed of one kind of a resin selected from the group consisting of high-density polyethylene, polypropylene, a cycloolefin polymer, and a methacrylate resin.
