PROBLEM TO BE SOLVED: To provide a method of joining a compound body of a Ni-based alloy layer and a steel material by which the strength of an interface and the peeling resistance thereof are increased, and to provide a joined body. SOLUTION: The method of joining a Ni-based alloy 2 containing nickel and a complex boride of molybdenum with a steel material 1 includes a step of bringing the Ni-based alloy 2 and the steel material 1 into contact with each other via a tungsten carbide layer after depositing the tungsten carbide layer on a surface of the Ni-based alloy 2 or the steel material 1, and a step of performing the metal bonding of the Ni-based alloy 2 and the steel material 1 by heating the Ni-based alloy 2 to the temperature at which a liquid phase appears, keeping it at the temperature, and cooling it later.
