NOVELTY - A protection sheet (1) has base material (11), and fluorine resin layer (12) laminated on the at least one surface of the base material. The fluorine resin layer is formed by hardening composition containing fluorine-containing polymer having energy-beam hardenable functional group, and energy-beam polymerization initiator by irradiating energy beam. The energy-beam polymerization initiator is chosen from phenoxy group-containing compound (I)-(IV).    USE - Protection sheet e.g. surface protection sheet and back surface protection sheet is used for solar cell module (claimed).    ADVANTAGE - The protection sheet has excellent weather resistance. The generation of blocking in the protection sheet is prevented. The discoloration of base material contained in the protection sheet is suppressed.    DETAILED DESCRIPTION - A protection sheet has base material and fluorine resin layer laminated on the at least one surface of the base material. The fluorine resin layer is formed by hardening composition (A) containing fluorine-containing polymer having energy-beam hardenable functional group, and energy-beam polymerization initiator by irradiating energy beam. The energy-beam polymerization initiator is chosen from phenoxy group-containing compound of formulae (I)-(IV).    R1-R10=H, alkyl, halo, alkoxy or phenoxy;and    X=S or O.    INDEPENDENT CLAIMS are included for the following:    (1) manufacture of protection sheet, which involves hardening non-hardened layer containing fluorine-containing polymer having energy-beam hardenable functional group, and polymerization initiator by irradiating energy beam, and laminating obtained fluorine resin layer on at least one surface of the base material; and    (2) solar cell module, which has sealing material, photovoltaic cell and protection components laminated on each main surface of the sealing material. At least one of the protection component contains protection sheet.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic sectional view of the protection sheet.
