A wire harness includes a terminated covered electric wire. The terminated covered electric wire includes a terminal fitting, an electric wire conductor, and an electrical connection portion in which the terminal fitting and the electric wire conductor are electrically connected to each other. The terminal fitting has a surface to which processing oil adheres, and the electrical connection portion is covered with an anticorrosive agent containing an adhesive resin and an oil-adsorbing organic macromolecule to configure a terminated covered electric wire.
