To provide a copper adhering terminal with excellent corrosion resistance for connecting an aluminum power transmission line with a copper bus bar of an electric power substation.

An aluminum body 10 has a fitting part 12 for fitting, compressing and connecting an aluminum power transmission line, and a copper plate jointing part 14 of the same shape as a copper plate 20. The aluminum body 10 and the copper plate 20 are metallically coupled with each other by a rotary press-fitting tool. The rotary press-fitting tool has a shoulder part 45 and a rod-like pin part 43 at a tip of a rod-like tool body 40. The copper plate jointing part 14 of the aluminum body 10 and the copper plate 20 are jointed and located on a rotary press-fitting tool stand 47, and linearly move at a desired portion while rotary press-fitting the pin part 43 from a surface of the copper plate 20. Therefore, a metal jointing part is formed on the copper plate jointing part 14 and the copper plate 20.
