Abstract: A solar cell module includes: solar cells each having a first main surface and a second main surface; a front-side transparent protective member disposed on a first main surface-side of the solar cells; a front-side transparent encapsulant layer disposed between the front-side transparent protective member and the solar cells; a back-side protective member disposed on a second main surface-side of the solar cells; a back-side white encapsulant layer disposed between the back-side protective member and the solar cells; and a back-side transparent encapsulant layer disposed between the back-side white encapsulant layer and the solar cells, wherein a thickness of the back-side transparent encapsulant layer in a vicinity of an edge portion of the second main surface of the solar cells is less than a thickness of the back-side transparent encapsulant layer in a region between the solar cells that are neighboring to each other.
