<p>A solar cell (1) is provided with a photoelectric conversion unit (2), and a collecting electrode (4), which is provided on the main surface of the photoelectric conversion unit (2). The collecting electrode (4) includes bus bars (19a, 19b), and fingers (20a-20d) that intersect the bus bars (19a, 19b), and each of the fingers (20a-20d) has a first finger portion (203), which extends with the line width thereof reduced toward the side away from the bus bar (19a, 19b) side, and a second finger portion (204), which continuously extends from the first finger portion (203), while maintaining the line width of a boundary portion (202) between the first finger portion (203) and the second finger portion. The length of the second finger portion (204) is shorter than that of the first finger portion (203).</p> |
