NOVELTY - A sealing resin sheet has a surface layer containing silane coupling agents laminated on at least one surface of a polyethylene-resin sheet. The polyethylene-resin sheet has area of 50 square.cm or more, and thickness of 50 mu m to 3 mm. The surface layer is laminated through a corona discharge treatment interface which corona-discharge-treats surface of polyethylene-resin sheet. The surface layer is film having thickness of 1-20 mu m and thickness distribution of 0.2 or less.    USE - Sealing resin sheet is used for solar-cell module (claimed).    ADVANTAGE - The sealing resin sheet having large area and excellent adhesiveness and uniformity is economically manufactured. The solar-cell module comprising the sealing resin sheet has excellent heat resistance, moisture resistance, hot-cold-cycle resistance?and damp-proof freezing property.    DETAILED DESCRIPTION - A sealing resin sheet has a surface layer containing silane coupling agents laminated on at least one surface of a polyethylene-resin sheet. The polyethylene-resin sheet has area of 50 square.cm or more, and thickness of 50 mu m to 3 mm. The surface layer is laminated through a corona discharge treatment interface which corona-discharge-treats surface of polyethylene-resin sheet. The surface layer is film having thickness of 1-20 mu m and thickness distribution of 0.2 or less and calculated using the relation: thickness distribution=(maximum thickness-minimum thickness)/(maximum thickness+minimum thickness). INDEPENDENT CLAIMS are included for the following:    (1) manufacture of sealing resin sheet, which involves coating organic-solvent solution of silane coupling agent by bar coating device on corona-discharge-treated interface and drying; and    (2) solar-cell module.
