PROBLEM TO BE SOLVED: To provide a joining method which can restrain change in the rigidity, shape and strength of joined portions of a joined member even when joining is performed by spark plasm sintering method, and can assure stable product quality; and to provide a joined member manufactured by the same method. SOLUTION: The invented joining method comprises two steps. In the step one, while a groove 10a provided on the front edge face 10A of a cope 10 is made to engage with a first joined portion 2, and a groove 11a provided on the front edge face 11A of a drag 11 which faces the front edge face 10A of the cope 10 is made to engage with a second joined portion 5, regions of the front edge face 10A of the cope 10 and the front edge face 11A of the drag 11 which do not touch the first joined portion 2 and the second joined portion 5 are made to touch directly. In the step two, pulse energization is made between the cope 10 and the drag 11 while pressing the first joined portion 2 and the second joined portion 5 by pressurizing the cope 10 and the drag 11 axially.
