PROBLEM TO BE SOLVED: To provide a back protection sheet for solar cell which does not generate gas when manufacturing a solar cell module, ensures excellent flexibility, heat resistance, and adhesiveness, and can be laminated on a solar cell by a roll-to-roll system when manufacturing a solar cell module.SOLUTION: In a back protection sheet A for solar cell, a sealing layer 3 is laminated integrally on any one side of a lamination sheet B where a weatherability substrate 2 is laminated integrally on a metal foil 1. The sealing layer 3 contains 100 pts.wt. of modified polypropylene resin that is graft-modified with unsaturated carboxylic acid or an anhydride and having a melting point of 120-170°C measured in accordance with JIS K7121, and 0.001-20 pts.wt. of silane compound represented by RSi(OR). |
