本发明提供种层叠体及其制造方法，其在对使用冷喷雾法而在基材形成金属皮膜的层叠体进行制造的情况下，使基材与金属皮膜之间的粘结强度高。本发明的层叠体(10)具备：由金属或合金形成的基材(1)；形成于基材(1)表面且由比基材(1)柔软的金属或合金构成的中间层(2)；通过使金属或合金的粉末材料与被加热为比该粉末材料的熔点低的温度的气体并加速，以固相状态直接向中间层(2)喷附并堆积在该中间层(2)上而成的金属皮膜(3)。 Provided is a method for manufacturing a lamination, in manufacturing a lamination in which a metal film is formed on a substrate using the cold spray method, having high adhesion strength between the substrate and the metal film. A lamination 10 according to the present invention includes a substrate 1 formed of a metal or alloy, an intermediate layer 2 formed on a surface of the substrate and is formed of a metal or alloy that is softer than the substrate 1, and a metal film 3 deposited by accelerating a powder material of a metal or alloy together with a gas heated to a temperature lower than the melting point of the powder material and spraying it onto the intermediate layer 2 while keeping it in a solid phase.
