PROBLEM TO BE SOLVED: To provide a method by which the contraction or the deformation of an electrodeposition part formed by masking using an insulating material can be prevented and the special shape of the electrodeposition part can be maintained for a cathode used for electrowinning of special shape electric nickel for plating. SOLUTION: An one-component epoxy resin is used as an insulating material applied on a cathode base plate for masking, and the kinetic viscosity of the resin is kept within a range of 10,000-30,000 cSt regardless of outside air temperature when the resin is applied. Further, concretely, the one-component epoxy resin is preheated so that the temperature Y (°C) of the resin satisfies following relation: Y= -0.82X+48.28, wherein X is outside air temperature, and the resin is applied on the cathode base material within one hour immediately after preheating.
