摘要
An object of the present invention is to provide a back sheet for a solar battery module that is less likely to cause a rise in temperature by irradiation with rays of the sun even though displaying a black color in appearance, and is less likely to discolor even after a long-term use thereof while suppressing a rise in cost. The back sheet for a solar battery module according to the present invention includes a colored layer that includes three or more types of color materials each having a different hue and a brightness L* of no less than 45, the colored layer having a brightness L' of no greater than 40. It is preferred that the three or more types of color materials are constituted with at least a red color material, a blue color material and a yellow color material. Preferably, a base sheet on which the colored layer is laminated is further included. It is preferred that the base sheet displays a white color and the colored layer is laminated on the front face side of the base sheet. Moreover, the base sheet preferably includes a base film and a white layer laminated on the front face side of the base film.
