PROBLEM TO BE SOLVED: To provide a tandem type organic photoelectric conversion element capable of exerting sufficient photoelectric conversion efficiency with excellent temperature-humidity cycle durability and bending durability.SOLUTION: In a tandem type organic photoelectric conversion element, at least two or more sub-cells 16a, 17a, 18a, 16b, 17b, 18b and a metal thin line pattern 14 arranged between the sub-cells are laminated. The metal thin line pattern is arranged on a face of a first sub-cell opposite to a second sub-cell. A portion of the metal thin line pattern nearer an inner side than 25% of a line width from a line edge of a face opposite to the second sub-cell has average roughness Ra of 20-100 nm. |
