A solar cell module having a solar cell panel with strings of electrically-coupled solar cells arranged in a row includes one or more lead wires that electrically couple the strings and a junction box. The one or more lead wires are arranged such that they do not overlap with each other and such that one or more of the lead wires includes a portion that overlaps and does not electrically connect to interconnector of a string. The lead wires include an interconnector connection part connected to a respective string interconnector, and the interconnector connection parts of the lead wires are arranged in a straight line.
