Abstract: The solar cell module of this invention reduces water reaching to a front surface glass in using a rear surface member of a resin film so as to suppress sodium deposited from the front surface glass from reaching to the front surface of the solar cell element. The solar cell module of this invention comprises a front surface glass, a rear surface resin film, a plurality of solar cell elements sealed with sealing resin between the front surface glass and the rear surface resin film, and a water transmission preventing layer arranged in a position including at least an interval part between the solar cell elements adjacent each other.

Abstract: A solar cell module including a plurality of solar cell elements 1 sealed by EVA resin between a front surface glass 20 and a rear surface member 5 is provided with a sodium diffusion preventing layer of a PET film 6 of a smaller water vapor transmission rate than those of the EVA sheets 3, 4 interposed between the front surface glass 20 and the solar cell elements 1.
