A bolt-fastened terminal connects to a wire that includes an aluminum core wire of an aluminum-based metal. The terminal includes a wire connection configured by a copper-based metal material and continuous with an electric contact that includes a bolt hole, the wire connection being welded and electrically connected to the aluminum core wire. A surface of the wire connection is coated with a first metal such as nickel and a surface of the electric contact is coated with a second metal such as tin. The first metal and the second metal, which are configured by different metals, are selected from metals between hydrogen and aluminum, aluminum having a negative electric potential with reference to the electric potential of hydrogen and a high ionization tendency, and the second metal is a metal having a smaller negative electric potential and lower ionization tendency than the first metal.
