PROBLEM TO BE SOLVED: To provide a novel ternary fluoropolymer sealant packed into the solar battery cells of a solar battery module, having assured waterproofness, optical properties such as transparency, processability, weathering resistance, acid resistance, alkali resistance, staining resistance, flexibility, adhesiveness, flame retardancy, etc., capable of being safely used for building materials such as roofs and walls and can provide an electric source having a high efficiency of light reception and electric generation. SOLUTION: In a solar battery module SM which performs the reception of light and the generation of electricity, the sealant of an output circuit to which solar battery cells 2 are connected is made of a binary or ternary fluoro polymer mainly consisting of tetrafluoroethylene(TFE), hexafluoroethylene(HFE) and vinylidene fluoride(VdF) or mainly consisting of TFE and VdF and having a melting point or having a controlled compositional ratio of 36-72 wt.%, 0-56 wt.% and 8-45 wt.%, respectively. |
