The interconnection conductive body includes conductive base strip, connective conductive strip, and out pole conductive strip. One end of the connective conductive strip and one end of the out pole conductive strip are welded on the conductive base strip respectively. The connective conductive strip and the out pole conductive strip are welded on the conductive base strip directly. Coating layeris coated on external surface of welded formed the interconnection conductive body. In condition of not influencing other performances of the interconnection conductive body, the invention reduces integral resistance of the interconnection conductive body, and raises reliability of connection among conductive base strip, connective conductive strip, and out pole conductive strip.
