Abstract

It is a method for manufacturing an electrode material containing Cu, Cr, a heat-resistant element, and a low melting metal. A Cr powder and a heat-resistant element powder are mixed together in a ratio such that the Cr is greater than the heat-resistant element by weight. The mixed powder of the heat-resistant element and the Cr powder is baked. A MoCr solid solution obtained by the baking and containing a solid solution of the heat-resistant element and the Cr is pulverized and then classified. The classified MoCr solid solution powder, a Cu powder, and a low-melting metal powder are mixed together, followed by sintering at a temperature that is 1010° C. or higher and is lower than 1038° C., thereby obtaining the electrode material.
