摘要: In diffusion bonding a metal pipe 112e and a metal pipe 114e via a bonded interface 116e formed at the end parts, a portion that is inclined with respect to the radial direction of metal pipes 112e and 114e is provided at least at part of bonded interface 116. In this case, the inclination angle &phgr; of bonded interface 116e and the tip angle 2&thgr; of a pipe expansion tool 130 are preferably in the relationship, 0
