PROBLEM TO BE SOLVED: To provide a solar battery module having a structure capable of reducing a stress difference between a part where a power generation element is laminated and a part where no power generation element is laminated.SOLUTION: Provided is a solar battery module 1 that comprises a lamination structure consisting of a front face layer L1, an encapsulation layer L2, and a back face layer L3, and in which a plurality of power generation elements 2 are arranged in the encapsulation layer L2. The solar battery module 1 is configured by a first lamination part 10 where the power generation element 2 is provided in the encapsulation layer L2, and a second lamination part 20 where no power generation element 2 is provided in the encapsulation layer L2. In the back face layer L3, a second part 5b that configures the second lamination part 20 is formed so as to be thicker than a first part 5a that configures the first lamination part 10.SELECTED DRAWING: Figure 1 |
