PROBLEM TO BE SOLVED: To provide a method of manufacturing a sintered metal joined body with which the development of defective joining is securely prevented by allowing brazing filler metal to sufficiently permeate at high speed into a gap between the joining surfaces of both metallic members to be joined, the effect caused by the dimensional variation of the metallic members at the sintering is restrained and a firmly joined sintered metal body can be obtained. SOLUTION: In the manufacturing method of the sintered metal joined body for joining, at the same time with sintering, a first metallic member 1 and a second metallic member 2 being unsintering metallic members, the first metallic member 1 having a recessed part 1a and a through-hole 3 is fitted into the second metallic member 2 having a projecting part 2a and grooves 7 radially extending from the projecting part 2a, and a laid. Furthermore, the brazing filler metal 4 is inserted into the through-hole 3, and these first metallic member 1, second metallic member 2 and brazing filler metal 4 are heated to execute the sintering and the brazing of the first metallic member 1 and the second metallic member 2.
