Provided is a solar battery module in which the distances between solar battery cells are different along interconnection wires and the concentration of a larger stress on the interconnection wires due to repeated temperature changes can be suppressed. The solar battery module (30) is equipped with a solar cell string (20) having a plurality of solar battery cells (10 to 14) arranged in an arrangement direction and at least two interconnection wires provided so as to extend along the arrangement direction in order to electrically connect the solar battery cells (10 to 14). The at least two interconnection wires include: a first interconnection wire (1) arranged at a first position where the distance between the solar battery cells adjacent to each other is short; and a second interconnection wire (2) arranged at a second position where the distance between the solar battery cells adjacent to each other is long. Bent portions are formed on the respective first and second interconnection wires (1, 2) between the solar battery cells, wherein the maximum value of the slope of the first interconnection wire (1) between the edge portions of the solar battery cells facing each other is larger than the maximum value of the slope of the second interconnection wire (2). |
