The present invention provides an electrode for a vacuum breaker excellent in fusion resistant property, and a vacuum breaker using it. An electrode for a vacuum breaker using an electrical contact in which refractory-metal particles are dispersed in an alloy of a highly conductive metal and a low melting-point metal, more specifically, Cr particles are dispersed in an alloy containing Cu and at least one kind out of Sn, Te, Bi is provided. A vacuum valve using the same, and a method for producing the electrical contact are also provided.
