To provide a brazing filler metal and a method for joining materials by using the brazing filler metal capable of joining more surely electrode materials or the like while maintaining the workability of the brazing filler metals even in the case of combination of metals somewhat different in a melting point.
Among metals composing multicomponent alloy brazing filler metals, a layer comprizing each of the metals composing a laminated brazing filler metal and multicomponent alloy brazing filler metals having an utmost outer layer composed of metals of a lowest melting point and an intermediate layer existing in the midst of the layers and comprising an other metal, is laminated so that the thickness of a layer of the metal of the lowest melting point becomes thicker than a ratio of thickness corresponding to an eutectic composition and thus the laminated brazing filler metal is made.
