  • Roughened nickel-plated material and method for manufacturing same
    Patent number: 12018395
    Abstract: [Object] To provide a roughened nickel-plated material in which the formation unevenness such as generation of the unevenness or grooves in a roughened nickel plated layer is restrained. [Solving Means] A roughened nickel-plated material including a base material that is a rolled material, and a roughened nickel plated layer formed on at least one surface of the base material, in which SRzjis of the surface of the roughened nickel plated layer is equal to or more than 2 ?m, and, letting a maximum height of the roughened nickel plated layer be SRz, a valley region B in a given virtual planer region A as observed at a height position of SRz×0.25 satisfies the following (i). (i) The length of the valley region B in the rolling direction RD of the base material is less than 40 ?m in a direct distance.
