A method for manufacturing an electrode material, comprising the steps of sintering a mixed powder containing a Cr powder and a powder of a heat-resistant element consisting of Mo,retained in a non-oxidizing atmosphere at a temperature of 900°C to 1200°C for 1 to 10 hours, the mixed powder containing the Cr and the heat-resistant element in a ratio such that the Cr is greater than the heat-resistant element by weight, thereby making a solid solution of the Cr and the heat-resistant element; pulverizing the solid solution of the Cr and the heat-resistant element to obtain a solid solution powder of the Cr and the heat-resistant element, and then classifying the solid solution powder of the Cr and the heat-resistant element such that a volume-based relative particle amount of particles having a particle size of 90 μm or less becomes 90% or greater; mixing the classified solid solution powder of the Cr and the heat-resistant element, a Cu powder having a median size d 50 of 100 μm or less, and a low melting metal powder having a median size d 50 of from 5 μm to 20 μm, the low melting metal powder being at least one selected from the group consisting of Bi, Sn, Se and Pb, such that the electrode material contains 39.80 to 89.73 weight % of the Cu, 7.96 to 47.86 weight % of the Cr, 1.99 to 11.96 weight % of the heat-resistant element, and 0.30 to 0.50 weight % of the low melting metal powder; and sintering a compact prepared by pressing a mixed powder obtained by the mixing step, at a temperature of from 1010 °C to 1035 °C, wherein the median particle size d 50 and the volume-based relative particle amount refer to values determined by a laser diffraction-type particle size distribution measurement apparatus CILAS 1090L, and wherein the upper limit or lower limit of the particle size of a powder is defined by a powder classified by a sieve having an opening of the upper limit value or lower limit value of the particle size. sintering a mixed powder containing a Cr powder and a powder of a heat-resistant element consisting of Mo,retained in a non-oxidizing atmosphere at a temperature of 900°C to 1200°C for 1 to 10 hours, the mixed powder containing the Cr and the heat-resistant element in a ratio such that the Cr is greater than the heat-resistant element by weight, thereby making a solid solution of the Cr and the heat-resistant element; pulverizing the solid solution of the Cr and the heat-resistant element to obtain a solid solution powder of the Cr and the heat-resistant element, and then classifying the solid solution powder of the Cr and the heat-resistant element such that a volume-based relative particle amount of particles having a particle size of 90 μm or less becomes 90% or greater; mixing the classified solid solution powder of the Cr and the heat-resistant element, a Cu powder having a median size d 50 of 100 μm or less, and a low melting metal powder having a median size d 50 of from 5 μm to 20 μm, the low melting metal powder being at least one selected from the group consisting of Bi, Sn, Se and Pb, such that the electrode material contains 39.80 to 89.73 weight % of the Cu, 7.96 to 47.86 weight % of the Cr, 1.99 to 11.96 weight % of the heat-resistant element, and 0.30 to 0.50 weight % of the low melting metal powder; and sintering a compact prepared by pressing a mixed powder obtained by the mixing step, at a temperature of from 1010 °C to 1035 °C, wherein the median particle size d 50 and the volume-based relative particle amount refer to values determined by a laser diffraction-type particle size distribution measurement apparatus CILAS 1090L, and wherein the upper limit or lower limit of the particle size of a powder is defined by a powder classified by a sieve having an opening of the upper limit value or lower limit value of the particle size. wherein the median particle size d 50 and the volume-based relative particle amount refer to values determined by a laser diffraction-type particle size distribution measurement apparatus CILAS 1090L, and wherein the upper limit or lower limit of the particle size of a powder is defined by a powder classified by a sieve having an opening of the upper limit value or lower limit value of the particle size.
