To provide a high-nickel plating bath which is weakly acidic and can stably form a plating film having a nickel content of 11 to 19% (preferably 12 to 18%) even at a current density of 3A/dm 2 or more. An acidic zinc-nickel alloy electroplating solution which contains an amine compound represented by the formula H 2 N-R1-R2 {wherein: R1 is [(CH 2 ) M -NH] L or (CH 2 ) N ; R2 is H, NH 2 or R3; R3 is an alkanol or alkoxyl group having 1, 2, 3, 4 or 5 carbon atoms; L is 2, 3, 4 or 5; M is 2, 3, 4 or 5; and N is 3, 4 or 5}. |
