Method for producing electrode material, and electrode material

The present invention is a method for producing an electrode material containing Cu, Cr, and a heat-resistant element. A heat-resistant element powder and a Cr powder are mixed in a ratio such that the heat-resistant element < Cr in terms of weight. This powder mixture of the heat-resistant element powder and the Cr powder is fired. The resulting sintered body contains a solid solution body that is a solid solution of the heat-resistant element and Cr. The sintered body is pulverized, and the resulting solid solution body powder is classified such that the grain diameter is less than 200µm. An electrode material is obtained by mixing and then sintering 10-60 parts by weight of the classified solid solution body powder and 90-40 parts by weight of a Cu powder. If a low-melting metal powder having a median diameter of 5-40µm is mixed into the powder mixture of the solid solution body powder and the Cu powder, adhesion resistance will be further improved.
