    摘要： An electrode material wherein Cr-containing particles are finely miniaturized and uniformly dispersed while a Cu portion, which is highly conductive component, is also finely miniaturized and uniformly dispersed. The electrode material is prepared, for example, by: a mixing step (S1) for mixing a Cr powder and a heat resistant element powder; a provisional sintering step (S2) for provisionally sintering the mixed powder to obtain a solid solution of Cr and the heat resistant element; a pulverizing step (S3) for pulverizing the solid solution of Cr and the heat resistant element to obtain a solid solution powder of Cr and the heat resistant element; a molding step (S4) for molding the solid solution powder; a main sintering step (S5) for performing main sintering of the obtained molded body to obtain a sintered body (skeleton) of Cr and the heat resistant element; and a Cu infiltration step (S6) for infiltrating the sintered body of Cr and the heat resistant element with Cu.A method for producing an electrode material, involving: (i) a step of preparing a powder of a solid solution of Cr and a heat resistant material selected from the group consisting of Mo, W, Ta, Nb, V and Zr, wherein either a peak corresponding to Cr element or a peak corresponding to the heat resistant element, which are observed by X ray diffraction measurement made on the powder of the solid solution, disappears; (ii) a step of molding the powder of the solid solution to obtain a molded body and then sintering the molded body to produce a sintered body; and (iii) a Cu infiltration step of infiltrating the sintered body with Cu.
