Laminated sheet and solar cell backsheet using same

A laminated sheet comprising:

• a two-layer sheet in which an L1 layer including 50 to 99 parts by mass of an ethylene-based polymer (E1) having a density of 890 to 970 kg/m3 and 1 to 50 parts by mass of a propylene-based polymer (P1) (in which the total of the component (E1) and the component (P1) is 100 parts by mass) is in contact with an L2 layer including 50 to 100 parts by mass of a propylene-based polymer (P2) and 0 to 50 parts by mass of an ethylene-based elastomer (E2) having a density of equal to or more than 850 kg/m3 and less than 890 kg/m3 (in which the total of the component (P2) and the component (E2) is 100 parts by mass),
• wherein the propylene-based polymer (P1) includes a propylene-based elastomer (P1a) including a propylene-derived constitutional unit and an ethylene-derived constitutional unit and/or a constitutional unit derived from an α-olefin having 4 to 20 carbon atoms, and satisfying the following requirement (a-1):
• (a-1) a melting point (Tm) as measured using a differential scanning calorimeter (DSC) is lower than 120° C. or the melting point (Tm) is not observed.
