PROBLEM TO BE SOLVED: To provide a solar cell capable of maximizing the efficiency.SOLUTION: A solar cell includes: a photoelectric conversion section; and a first electrode 24 and a second electrode that are connected to the photoelectric conversion section. At least one of the first and second electrodes includes a plurality of finger electrodes 24a, and at least one bus bar electrode 24b formed in a direction crossing the plurality of finger electrodes. The bus bar electrode includes a main bus bar 241b, and an auxiliary bus bar 242b formed adjacently to the main bus bar across a separation space. The separation space has a width equal to or less than a pitch of the plurality of finger electrodes. |
