Abstract: Disclosed is a solar cell panel including a plurality of solar cells each including a semiconductor substrate and an electrode formed on the semiconductor substrate, and a wire for interconnecting the solar cells. The electrode includes a bus-bar line having a pad portion for attachment of the wire. The wire includes a first wire portion connected to the pad portion, and a second wire portion located on a portion excluding the pad portion. The first wire portion has a thickness greater than a thickness of the second wire portion.
