Abstract:
A solar cell lead wire includes a molten solder plated layer on a strip-shaped conductive material formed rectangular in a cross section thereof so as to be bonded by soldering to an electrode of a solar cell, using a flux. A thickness of an oxide film on a surface of the molten solder plated layer, which is a sum of a thickness of an SnO layer and a thickness of an SnO2 layer on the surface of the molten solder plated layer, is not more than 7 nm.
