Abstract: The solar battery module according to one embodiment of the present invention is provided with: multiple solar battery cells; a first protective member, a second protective member, a first wiring material for connecting adjacent solar cells; and a second wiring material for connecting strings, that have been obtained by connecting the multiple solar cells via the first wiring material, to each other. The first wiring material and/or the second wiring material has a conductive core material and a colored layer that covers a surface on the side of the core material that faces the first protective member. The colored layer absorbs at least 30% of visible light having a wavelength of 380-780 nm.

Abstract: A solar cell has multiple busbar electrodes formed at intervals and multiple finger electrodes formed between the busbar electrodes. The finger electrodes comprise multiple finger parts connected only to one busbar electrode and multiple finger parts connected to only another busbar electrode. The adjacent multiple finger parts are connected to one another, and the adjacent multiple finger parts are connected to one another.
