Brazing Apparatus and Assembly-Brazing Method

A brazing method for joining a plurality of parts forming an assembly, the method comprising:

• placing the assembly on or above a stage with a brazing material being interposed between the joint surfaces of a plurality of to-be-joined materials;
• applying a pressure to the assembly, which is placed on or above the stage, toward the stage by using a pressure applier;
• heating the assembly under the pressure to a predetermined temperature that melts the brazing material;
• and
• applying ultrasonic vibration to at least one of the stage and the pressure applier with the assembly under the pressure having been heated to the predetermined temperature, wherein
• oxide film on the joint surfaces of the plurality of to-be-joined materials forming the assembly is removed by vibrating the stage and the pressure applier relative to each other by applying ultrasonic vibration in the applying ultrasonic vibration.
