Abstract: Provided are: a sealing material sheet for solar cell modules, and a sealing material-integrated rear-surface protecting sheet. A sealing material sheet 1 for solar cell modules, which has a thickness of from 200 μm to 400 μm (inclusive) and comprises a core layer 11 and a skin layer 12, and wherein: the core layer 11 contains from 5% by mass to 40% by mass (inclusive) of a polypropylene and from 60% by mass to 95% by mass (inclusive) of a low-density polyethylene having a density of from 0.910 g/cm3 to 0.940 g/cm3 (inclusive) in terms of content ratios to all the resin components; and the skin layer 12 contains from 80% by mass to 100% by mass (inclusive) of a low-density polyethylene having a density of 0.880 g/cm3 or more but less than 0.910 g/cm3 in terms of a content ratio to all the resin components, without containing a polypropylene.
