In an iron tip for a soldering iron, composed of Fe plated copper or copper alloy, an outer surface excluding a solder coating portion in a leading end portion of the iron tip is plated with Cu in a film thickness range of approximately 10 to 50 mum, the surface is coated with a mixture of Al particles and flux, only the Al particles are melted in an inert gas atmosphere, and the surface is modified into a surface with a Cu-Al alloy coated layer having a high Al concentration. As a result, without using Cr plating, it is possible to provide an electric soldering iron having an excellent resistance to oxidation under high temperature environment and a high heat conductivity.
