PROBLEM TO BE SOLVED: To provide a surface decoration structure provided with a silver mirror film layer having good glossiness, and good corrosion resistance, and a method of forming the same.SOLUTION: The surface decoration structure 10 is formed with an under coat coated film 12, a silver mirror film layer 13, and a topcoat coated film 14 on a substrate surface. The silver mirror layer 13 is formed with a film in a state of laminating silver particles having a nanometer size coated with a polymer dispersant on the surface thereof. The topcoat coated film 14 is formed using at least one solvent selected from the group consisting of an aliphatic hydrocarbon compound, an aliphatic hydrocarbon compound solution containing not greater than 10 mass% of an aromatic compound, and diisobutyl ketone. At least one of the under coat coated film 12 and the topcoat coated film 14 may contain an anti-rust agent, and further the silver mirror film layer 13 may also contain an anti-rust agent.SELECTED DRAWING: Figure 1 【課題】良好な光沢を有し、しかも耐食性が良好な銀鏡膜層を備えた表面装飾構造及びその形成方法を提供すること【解決手段】基体表面に下塗り塗膜１２、銀鏡膜層１３及び上塗り塗膜１４が形成された表面装飾構造１０において、銀鏡膜層１３は、表面に高分子分散剤が被覆されたナノメーターサイズの銀粒子が積層された状態で膜を形成しており、上塗り塗膜１４は、溶媒として、脂肪族炭化水素化合物、１０質量％以下の芳香族化合物を含む脂肪族炭化水素化合物溶液及びジイソブチルケトンから選択された少なくとも１種を含むものを用いて形成されたものからなる。下塗り塗膜１２、上塗り塗膜１４の少なくとも一方には防錆剤が含有されていてもよく、さらには銀鏡膜層１３にも防錆剤が含有されていてもよい。【選択図】図１
