Abstract
A resistance welding electrode for supplying a current to metal workpieces to weld the workpieces to each other includes an electrode body as an electrode matrix of a copper alloy and a plurality of filamentary members embedded in the electrode matrix parallel to the direction in which a current flows therethrough. The filamentary members have respective tip ends exposed as lands on a surface of a tip end of the electrode body. The filamentary members are made of a material having an electric conductivity different from that of the electrode matrix. The exposed tip ends of the filamentary members having a total area which is in the range of 0.5 to 40% of the entire area of the tip end of the electrode body.
