A solar cell module includes a solar cell string, a first encapsulant, a second encapsulant having a viscoelasticity greater than a viscoelasticity of the first encapsulant, a front-side protective plate, and a back-side protective sheet. The solar cell string includes a plurality of solar cells and a line member which electrically connects the plurality of solar cells. The lengthwise direction of the line member is different from the maximum expansion and contraction direction of the back-side protective sheet.

A solar cell module includes a solar cell, a wiring member electrically connected to the solar cell, a light-receiving-surface encapsulant and a back-surface encapsulant that cover the solar cell, a light-receiving-surface protecting member; and a back-surface protecting member. The back-surface protecting member does not contain a metal foil. A back-side metal electrode contacts the back-surface encapsulant. The arithmetic mean roughness of the surface of the back-side metal electrode that contacts the back-surface encapsulant is less than 0.1 μm. The back-surface encapsulant comprises a crosslinked olefin resin.
