[Problem] When conductors are connected to one another, conventionally the conductors are plated with silver or tin, which are conductive and corrosion resistant, in order to prevent the formation ofoxide films on the surface of the conductors, and to prevent electrolytic corrosion resulting from different types of metal coming into contact with one another. Plating the entire conductor results in an increase in cost, and partial plating requires the addition of a masking operation, and depending on the shape of the conductor, may result in a cost that is higher than coating the entire conductor. [Solution] According to the present invention, when conductors are to be connected using a fastener, an electrically conductive member for connection of conductors is interposed between the two conductors. A plurality of protruding portions are formed on the surfaces, of the electrically conductive member for connection of conductors, that come into contact with the conductors. A plating layer is formed on the contacting surfaces that include the protruding portions, by means of an electrically conductive and corrosion-resistant plating process. When the conductors are connected to one another using a fastener, the contact pressure of the protruding portions causes oxide films on the electrically conductive member for connection of conductors to be removed.
