PROBLEM TO BE SOLVED: To provide a soluble anode for Sn alloy electrolysis plating capable of providing metal ions of Sn and an additive component thereof from an anode when Sn alloy such as Sn-Ag-based alloy and Sn-Cu-based alloy are electrolysis plated.SOLUTION: In a soluble anode for Sn alloy electrolysis plating 1, a first anode body 2 consisting of Sn and a second anode body 3 consisting of an additive component of the Sn alloy are laminated alternately for covering a whole area each other and an outer peripheral surface and an inner peripheral surface of the laminate are covered by an encapsulation body 4, the second anode body 3 exposed to a top face of both anode bodies is eluted, then the first anode body 2 is eluted as the first anode body 2 is exposed when elution of the second anode body 3 is finished.SELECTED DRAWING: Figure 1 |
