Abstract
A roughened nickel-plated sheet including a roughened nickel layer on at least one surface of a metal substrate as the outermost layer thereof, the roughened nickel layer being formed of a plurality of nickel protrusions. When the structure of the roughened nickel-plated sheet is observed at height positions with a focused ion beam scanning electron microscope (FIB-SEM), the absolute value of the change rate of the nickel occupancy is equal to or less than a predetermined value, and the nickel occupancy and the number of nickel protrusions present at a height position located 2.0 μm from the base position of the roughened nickel layer toward the surface in the height direction are equal to or more than predetermined values, respectively.
