An interconnector includes a front surface electrode connecting portion connected to a front surface electrode of a solar cell, a back electrode connecting portion connected to a back electrode of another solar cell adjacent to the solar cell, and a stress relief portion absorbing displacement generated between the front surface electrode connecting portion and the back electrode connecting portion. A plurality of notches are formed at the front surface electrode connecting portion and the back electrode connecting portion. Since the front surface electrode connecting portion and the back electrode connecting portion have notches, an area sufficient for welding can be ensured. Reliability at the joining portion of the interconnector can be improved. Also, the interconnector can be reduced in size to allow reduction in cost.
