PROBLEM TO BE SOLVED: To provide a solder plated wire having high resistance to repeated bending, and a solar cell module.SOLUTION: The solder plated wire includes a conductor and a solder plated layer included on the outer periphery of the conductor. The conductor consists of a wire in which the area of crystals consisting of a grain size of 30 μm or more exists at a ratio of 2% or more to the entire area of crystals existing on the cross section when any cross section is observed.SELECTED DRAWING: Figure 1 【課題】繰り返しの屈曲に対する耐性が高いはんだめっき線および太陽電池モジュールを提供する。【解決手段】本発明の一態様において、導体と、導体の外周に有するはんだめっき層と、を備え、前記導体は、任意の断面を観察したときに、３０μｍ以上の結晶粒径からなる結晶の面積が前記断面に存在する結晶の全体の面積に対して２％以上の割合で存在する線材からなるはんだめっき線を提供する。【選択図】図１
