PROBLEM TO BE SOLVED: To provide a solar battery-sealing film which allows the effect of a fluorescent material increasing a power generation efficiency to be kept at a high level even in the case of using the solar battery-sealing film over a long period of time.SOLUTION: A solar battery-sealing film 13A, 13B comprises: a resin material including olefin (co)polymer; and a wavelength conversion material. The wavelength conversion material includes at least one inorganic fluorescent material selected from materials expressed by the formula (I) or (II) below, and a transparent material consisting of a (meth)acrylic resin: BaMgAlO:Eu,Mn(I)(where "a" is 0.05-0.25, and "b" is 0.10-0.40); and BaMgAlO:Eu,Mn(II)(where "c" is 0.05-0.25, and "d" is 0.20-0.80). The content of the at least one inorganic fluorescent material is 0.0001-0.005 pt.mass to 100 pts.mass of the resin material. |
