Provided is a solar cell interconnector material characterized by having, on an Al substrate surface, a 0.2mum or thicker Ni plating layer, and a Sn plating layer, in that order from the substrate side. By means of this invention, it is possible to provide a solar cell interconnector material and a solar cell interconnector which are comparatively cheap while containing essentially no copper, and which effectively prevent problems such as peeling and cracking of coatings due to the thermal history of soldering.
