PROBLEM TO BE SOLVED: To provide a lead wire for a solar battery excellent in bondability to a solar battery cell.SOLUTION: In a storage method of a lead wire 10 for a solar battery formed by coating a band plate-shaped conductive material 12 whose cross-sectional shape is processed in a flat square shape with a fused solder plating layer 13, the lead wire 10 for the solar battery is stored at a temperature of 30°C or lower and at a relative humidity of 65% or lower in the unpacked state or in the packaging material open state so that the thickness of an oxide film on the surface of the fused solder plating layer 13 is kept at 7.0 nm or thinner. |
