Provided is a method for bonding metal members, the method comprising: a laminate forming step (S10) for forming a laminate by inserting an insert material between a first metal member and a second metal member that are each formed of a carbide-containing Ni alloy or a carbide-containing Fe alloy; and a solid phase diffusion bonding step (S12) for performing solid phase diffusion bonding by heating and pressurizing the laminate to form a metal member assembly, wherein the insert material has a higher Ni content than the Ni content of the first and second metal members when the first and second metal members are each formed of a carbide-containing Ni alloy, and has an Fe or Ni content that is higher than the Fe contents of the first and second metal members when the first and second metal members are each formed of a carbide-containing Fe alloy.
