An electrode of a vacuum circuit breaker, having a high dielectric strength, large breaking current and superior non-welding characteristic. The electrode is made of a cast alloy comprising copper, 20 wt% or less of rare earth metal such as lanthanum, cerium or an alloy of either one of these rare earth metal with another rare earth metal, 10 wt% or less of a metal such as lead and bismuth having a lower melting point and a higher vapor pressure than copper, and 0.1 to 30 wt% of a metal of iron group. A part of the rare earth metal and a part of the metal having the lower melting point and higher vapor pressure than copper are crystallized in the grain boundary and in the grains of copper.
