<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing electric nickel for special shape plating, by which a part discolored to black does not occur on the base plate surface of an electrodeposited material even when plating is carried out with high current density to enhance productivity. Ž<P>SOLUTION: In the method of manufacturing electric nickel for special shape plating, a cathode whose surface is masked to obtain special shape electrodeposition and which has an electrodeposition part, is used, and a nickel chloride solution containing a sulfur source and having 68-95 g/L nickel concentration and pH2.4-4.0 is used as an electrolyte and current density is made 1,100-1,350 A/m<SP>2</SP>, to preferably satisfy a relation expressed by formula Y≥0.03X+35.63 when the current density is defined as X (A/m<SP>2</SP>) and the nickel concentration is defined as Y (g/L) in the nickel chloride solution.
