PURPOSE: To produce easily an electrode material for welding having excellent conductivity of electricity and heat without abnormal generation of heat during use by providing a specific coating layer dispersed with oxide, carbide, etc. on the surface of a copper alloy.

CONSTITUTION: The dispersion type alloy coating layer 4 is provided on the surface at the tip 3 of the copper alloy 1. The dispersion type alloy is made by using a metal or alloy, for example, Co, Cr, W, Mo, Ni, Ti, etc. or the alloy thereof, etc. as a base and dispersing particles of oxide, carbide, nitride or carbonitride, for example, chromium carbide, tungstan carbide, titanium carbide, etc. therein. A method such as electroplating, electroless plating or vapor deposition method is used to form the dispersion type alloy coating layer.
