PROBLEM TO BE SOLVED: To provide a laminate capable of correcting deformation generated in a manufacturing process, and capable of forming a desired shape in the laminate having a metallic film on a metallic base material formed by a cold spraying method.SOLUTION: A laminate includes a base material formed of a first metal or alloy and having a main surface 11a and a main surface 11b facing each other, and a film 12 formed on the main surface 11a by accelerating powder made of a second metal or alloy together with gas and spraying the powder kept in a solid state onto the main surface 11a to be deposited. An end region 111 in a thickness direction on the main surface 11a side of the base material 11 has first residual compressive stress, and an end region 112 in the thickness direction on the main surface 11b side in the base material 11 has second residual compressive stress. |
