A solar cell module comprising: a solar cell element having a front surface busbar electrode disposed on the front main surface of a semiconductor substrate and a rear surface busbar electrode disposed on the rear main surface of the semiconductor substrate; a first connection tab disposed on the front surface busbar electrode and having one end section disposed on a first side surface-side of the semiconductor substrate; a first solder connecting the front surface busbar electrode and the first connection tab; a second connection tab disposed on the rear surface busbar electrode and having one end section disposed on the second side surface-side of the semiconductor substrate; and a second solder connecting the rear surface busbar electrode and the second connection tab. In order to reduce the generation of cracks by reducing the stress generated in the solar cell element when soldering the connection tabs to the busbar electrodes on the solar cell element, on the first side surface-side and the second side surface-side of the semiconductor substrate, the longitudinal ends of a first bonding surface where the first solder is bonded to the front surface busbar electrode are positioned further outside than the longitudinal ends of a second bonding surface where the second solder is bonded to the rear surface busbar electrode. |
