    摘要: PROBLEM TO BE SOLVED: To provide a nickel plating solution and its preparation method, and a nickel plating method, which are suitable for nickel or nickel alloy plating to be applied to printed wiring board copper foil, and capable of continuously performing stable plating even in the use of an insoluble anode and reducing the load on the environment, and to provide printed wiring board copper foil with good adhesion to a printed wiring board base material. SOLUTION: The printed wiring board copper foil 7 has a nickel plating layer (nickel-cobalt alloy plating layer 3) applied by a nickel plating method using a nickel plating method solution prepared by dissolving in water 100 g/L or more and less than 200 g/L of nickel sulfate, and 10 g/L or more and less than 30 g/L of sodium citrate or 8 g/L or more and less than 25 g/L of citric acid, but adding no nickel chloride; and adjusting the pH of the resultant solution to 2 or more and less than 4 and using the insoluble anode as the anode.
