[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 of 
oxide 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.
