The purpose of the present invention is to provide a solar cell module back sheet, the temperature of which hardly rises by being irradiated with solar rays even if taking on a black color in appearance and the color of which hardly changes even if being used over a long period of time while a cost increase is suppressed. This solar cell module back sheet is equipped with a colored layer including three or more kinds of color materials each having a different hue and a lightness value (L*) of 45 or more, wherein said colored layer has a lightness value (L*) of 40 or less. It is preferable that said three or more kinds of color materials are at least a red color material, a blue color material, and a yellow color material. It is also preferable that the solar cell module back sheet is equipped with a base sheet on which said colored layer is laminated. It is preferable that said base sheet is colored white and said colored layer is laminated on the surface side of said base sheet. It is also preferable that the base sheet is equipped with a base film and a white layer laminated on the surface side of said base film. |
