To provide a manufacturing method of a silver plated body in which adhesive force between a silver plated layer and a top coat layer is improved.SOLUTION: In a manufacturing method of a silver plated body having at least an undercoat layer, a silver plated layer and a top coat layer in this order on a substrate, the top coat layer is formed, by applying on the substrate and by bridging a coating composition containing at least an acrylic polyol resin, a compound having two or more isocyanate groups and a compound having two or more carbodiimide groups.SELECTED DRAWING: None 【課題】銀めっき層とトップコート層の間の接着力が改善された銀めっき塗装体を得ることができる製造方法を提供すること。【解決手段】基材上に、少なくともアンダーコート層、銀めっき層及びトップコート層をこの順に有する銀めっき塗装体の製造方法において、該トップコート層を少なくともアクリルポリオール樹脂、２個以上のイソシアネート基を有する化合物及び２個以上のカルボジイミド基を有する化合物を含有する塗料組成物を基材上に塗布し、架橋することによって形成する。【選択図】なし
