Summary:PROBLEM TO BE SOLVED: To provide a lead wire for a solar cell that is hard to be broken at a portion wired between neighboring solar cells when used for a solar cell module even in the case of a low proof stress and a solar cell module including the same.SOLUTION: A lead wire 10 for a solar cell includes: a rectangular conductor made of pure copper or a copper alloy; and a surface layer made of a Cu-Ag alloy provided at an outer periphery of the rectangular conductor. The total 0.2% proof stress value is less than or equal to 90 MPa.SELECTED DRAWING: Figure 1 【課題】低耐力の場合でも、太陽電池モジュールに用いた際に隣り合う太陽電池セル間に配線された部分において破断が生じにくい太陽電池用リード線及び当該太陽電池用リード線を用いた太陽電池モジュールを提供する。【解決手段】太陽電池用リード線１０は、純銅又は銅合金からなる平角導体と、前記平角導体の外周に設けられたＣｕ−Ａｇ合金からなる表面層とを備え、全体の０．２％耐力値が９０ＭＰａ以下である。【選択図】図１
