PROBLEM TO BE SOLVED: To provide a paste-like composition for aluminum brazing, a composition superior in applicability and dimensional accuracy of a brazed product, erosion resistant, and excellent in the appearance of a fillet of brazed joint, and also to provide an aluminum-containing member applied with the composition and a method of brazing the aluminum-containing member using the composition. SOLUTION: The paste-like composition for aluminum brazing contains an aluminum-containing powder. In a cumulative particle size curve of the aluminum-containing powder, where D(Q)μm is a grain diameter Dμm corresponding to a Q vol.% , the composition is such that D(50)μm is 20-150μm, that D(90)μm/D(10)μm is≤5, that mass ratio of particles in the aluminum-containing powder passing through the sieve of 45μm mesh opening is≤50%, and that the degree of fluidity of the aluminum-containing powder is≤80 s/50 g.
