PROBLEM TO BE SOLVED: To provide a method for manufacturing an electrode material by which an electrode material superior in voltage resistance can be manufactured at lower cost.SOLUTION: A method for manufacturing an electrode material comprises the steps of: molding mix powder consisting of a mixture of Cu powder, Cr powder, and powder of refractory metal (e.g. Mo) by compression; and sintering the resultant mold in a non-oxidizing atmosphere at a temperature of a Cu melting point or lower. As the Cr powder mixed in the mix powder, Cr powder of particles having diameters of 40 μm or smaller, of which the volume relative particle amount is less than 10% is used. In the mix powder, the Cr powder is mixed by 10 to 50 wt.%, and the refractory metal powder is mixed by 1 to 10 wt.%. |
