A solar cell includes a photoelectric converter having n-type regions and p-type regions alternately arranged in a first direction on a back surface and an electrode layer provided on the back surface. The photoelectric converter includes a plurality of sub-cells arranged in a second direction intersecting with the first direction and an isolation region provided on a boundary between adjacent sub-cells. The electrode layer includes an n-side electrode provided on the n-type region in the sub-cell at the end of the sub-cells, a p-side electrode provided on the p-type region in the sub-cell at the other end, and a sub-electrode provided over two adjacent sub-cells. The sub-electrode connects the n-type region provided in one sub-cell of the two adjacent sub-cells to the p-type region provided in the other sub-cell.
