PROBLEM TO BE SOLVED: To provide solder plated wire capable of improving bending life and a solar cell module using the same.SOLUTION: Solder plated wire 10 includes: a conductor 1; and a solder plating 2 on a surface of the conductor 1. The conductor 1 has a substantially rectangular transverse cross section. When five regions equally divided into five pieces in a long side direction of the substantially rectangular shape are denoted as a left end portion B, a left middle portion D, a middle portion A, a right middle portion E, and a right end portion C from the left end to the right end in the long side direction, the hardness of the left end portion B and the right end portion C is harder than the hardness of the middle portion A.SELECTED DRAWING: Figure 1 【課題】屈曲寿命の向上が可能なはんだめっき線及び当該はんだめっき線を用いた太陽電池モジュールを提供する。【解決手段】はんだめっき線１０は、導体１と、導体１の表面上のはんだめっき２と、を備え、導体１は、横断面が略矩形形状であって、前記略矩形形状の長辺方向に５等分した５領域を前記長辺方向の左端から右端にかけて左端部Ｂ、左中間部Ｄ、中央部Ａ、右中間部Ｅ、右端部Ｃとした場合に左端部Ｂ及び右端部Ｃの硬さが中央部Ａの硬さよりも硬いことを特徴とする。【選択図】図１
