Abstract: Provided is a bonded body of copper alloy and steel material that has high bonding property at the interface of the copper alloy and the steel material, and is capable of maintaining a high strength without carrying out the subsequent precipitation hardening process accompanied by solution annealing (or by carrying out only the precipitation hardening process that is not accompanied by the solution annealing). This bonded body includes a first member composed of a precipitation-hardenable copper alloy and a second member including an additively manufactured object made of a steel material bonded to the first member at at least one bonding interface. The bonded body, when the cross section perpendicular to the bonding interface is observed by a scanning electron microscope (SEM), is free of voids having a length of 50 μm or more at the bonding interface in a direction parallel to the bonding interface.
