NOVELTY - A polymer sheet comprises polymer support (16), polymer layer (1) arranged on one surface (A) of the polymer support, polymer layer (2) arranged between the surface (A) of the polymer support and layer (1), polymer layer (3) arranged on a surface (B) of the polymer support, and polymer layer (4) arranged on the polymer layer (3). The layer (1) contains pigment. The layer (2) contains polymer chosen from polyolefin resin, acrylic resin and polyester resin. The layer (3) contains silicone polymer. The layer (4) contains fluorine-containing polymer.    USE - Polymer sheet is used for solar cell backsheet for solar cell module (all claimed).    ADVANTAGE - The solar cell module obtained by the solar cell backsheet containing the polymer sheet prevents delamination between the polymer sheet and sealing material, and has excellent stability, electric power generation efficiency, weather resistance, and reliability.    DETAILED DESCRIPTION - A polymer sheet comprises polymer support, polymer layer (1) arranged on one surface (A) of the polymer support, polymer layer (2) arranged between the surface (A) of the polymer support and layer (1), polymer layer (3) arranged on a surface (B) of the polymer support which is opposed to the surface (A), and polymer layer (4) arranged on the polymer layer (3). The layer (1) contains pigment, and has peel force against sealing material (22) of 5 N/cm or more. The layer (2) contains polymer chosen from polyolefin resin, acrylic resin and polyester resin. The layer (3) contains silicone polymer. The layer (4) contains fluorine-containing polymer. An INDEPENDENT CLAIM is included for manufacture of polymer sheet, which involves sequentially laminating the polymer layer (2) and polymer layer (1) on one surface (A) of the polymer support, and sequentially laminating the polymer layer (3) and polymer layer (4) on the surface (B) of the polymer support.
