PROBLEM TO BE SOLVED: To provide a joint portion return current bridging circuit for a railway rail, having a spot welded portion improved un soundness for a long period and offering a long service, and its forming means. SOLUTION: A current portion for forming the return current bridging circuit for a railway rail is formed by spot welding an anticorrosive metal foil to the railway rail or the polished surface of a joint plate. The polished surface and the surface of the anticorrosive metal foil are covered with an oil film layer.
