PROBLEM TO BE SOLVED: To provide a powder rolling method with which powder in formed into a plate-like or bar-like formed product having small electric resistance and high bonding strength among the powders and hardly developing the breakage by bending, etc., without damaging the characteristic possessed by the powder, and the apparatus therefor. SOLUTION: The objective powder having electric conductivity at least on the surface and the lower m.p. metal powder than that of the objective powder, are pre-mixed to form the electric conductive powder 9. The electric conductive powder is poured between one pair of rolls 12 arranged parallel to each other and electricity is supplied between the rolls, and the objective powders are welded by melting only the low m.p. metal powder by the resistant heating through the electric supply. |
