Cells including a first electrode layer, a photoelectric conversion layer, and a second electrode layer on a translucent substrate are connected. Between adjacent cells, a first separating groove separates the first electrode layer, a second separating groove separates the second electrode layer, and a connecting groove electrically connects the second electrode layer of a cell and the first electrode layer of the other. A reflective film is provided on the second electrode layer having a transparent conductive film and a metal film stacked in this order on the photoelectric conversion layer and at least the metal film is patterned into lines. The metal film is patterned into lines with a same width within the connecting groove and is connected to the first electrode layer of the adjacent cell. The reflective film is provided in the connecting groove where the metal film is not formed and in the second separating groove.
