A solar cell of the invention includes a photoelectric conversion section (50) and a collecting electrode (70). The photoelectric conversion section (50) has a first principal surface and a second principal surface, and the collecting electrode (70) is formed on the first principal surface. The collecting electrode (70) includes a first electroconductive layer (71) and a second electroconductive layer (72) in this order from the photoelectric conversion section (50) side, and includes an insulating layer (9) between the first electroconductive layer (71) and the second electroconductive layer (72). The insulating layer (9) is provided with an opening, and the first electroconductive layer (71) and the second electroconductive layer (72) are in conduction with each other via the opening provided in the insulating layer (9). The solar cell has, on the first principal surface, the second principal surface or a side surface of the photoelectric conversion section, an insulating region freed of a short circuit of front and back sides of the photoelectric conversion section, and the surface of the insulating region is at least partially covered with the insulating layer. |
