Summary:PROBLEM TO BE SOLVED: To provide a joined body excellent in joining strength in a joined body between ferrous alloy members joined by diffusion joining and a joining method. SOLUTION: In a joined body 6 obtained by diffusely joining two or more members 1 and 2 made of a ferrous alloy, the joint part of those members is provided with a joining layer 4 in which the content of nickel is <=40 mass %, thickness is <=2.0 mm, and also, the number of boron compounds having a diameter of >=1 μm in the cross section is <=2 pieces on the average per 50 μm.
