PROBLEM TO BE SOLVED: To provide a brazing method in which the strength and corrosion resistance of a member to which a female thread is formed can be sufficiently secured, and at the same time, the female thread forming member can be brazed more rationally. SOLUTION: The brazing method in which a plurality of aluminum members are integrally brazed by using a fluoride system flux with an atmosphere of an inert gas, is so constituted that at least one of the plurality of aluminum members is the female thread forming member to which the female thread to be screwed with a bolt is formed, the magnesium content of the female thread forming member is 0.40-0.70 [wt.%], and furthermore, the magnesium content of the other aluminum member which is brazed with the female thread forming member is smaller than the female thread forming member.
