Abstract
There is disclosed a method for manufacturing an electrode by pressing and sintering a mixed powder of a solid solution powder of Cr and a heat-resistant element, which contains Cr and the heat-resistant element in a ratio such that Cr is greater than the heat-resistant element by weight, a Cu powder, and a low melting metal powder (Bi, Sn, Se, Pb, etc.). The low melting metal powder of 0.30 weight % to 0.50 weight % is added to a mixed powder of a solid solution powder of Cr and the heat-resistant element and the Cu powder, and then a mixed powder prepared by adding the low melting metal powder is sintered at a temperature of from 1010° C. to 1035° C. As the low melting metal powder, there is used a powder having a median size of from 5 μm to 20 μm.
