(57) [Problem] To join a metal containing at least one of Fe and Ni as a main component, a liquid phase diffusion bonding method with less heat input concentration is employed, and a metal bonded body obtained is obtained. Provided is a method for manufacturing a metal joined body that can improve the joint properties of a joint interface and can obtain a joined body with higher strength. SOLUTION: An insert material 3 containing B is used, and F is used. Liquid phase diffusion bonding is performed by interposing between members to be bonded containing e and / or Ni as a main component. In this joining step, the liquid phase 4 The first and second members to be joined 1 and 2 in the state where Is pressurized in the direction in which the liquid phase 4 is compressed, whereby the joint characteristics of the joining interface of the resulting metal joined body are greatly improved, and a joined body having higher strength can be obtained. |
