ABSTRACT:
A resistance welding electrode for supplying a current to metal workpieces to weld the workpieces to each other has an electrode matrix of a copper alloy and a plurality of members disposed in the electrode matrix and having portions exposed on a surface of a tip end of the electrode matrix. The members are made of a material having an electric conductivity different from that of the electrode matrix. The exposed portions of the members have a total area which is in the range of 40 to 82% of the entire area of the tip end of the electrode matrix.
