Nickel-plated metal material

Abstract

[Object] Disclosed is a nickel-plated metal material, which has adhesion with another member while suppressing the height of a roughened nickel layer. [Solving Means] The nickel-plated metal material includes a base material made of metal and a roughened nickel layer formed on at least one side on the base material. A ten-point mean roughness Rzjis on an outermost surface on a side of the roughened nickel layer of the nickel-plated metal material is 1.0 μm or greater and smaller than 4.8 μm, and a roughened surface area on the outermost surface on the side of the roughened nickel layer is 1.5 m2/1 m2 or greater.
