Zusammenfassung:	To provide a silica-based film having design properties (texture) similar to a film using a glaze and a hardness similar to the film using a glaze.SOLUTION: A silica-based film 1 contains a polymer soluble in alcohol. A hybrid matrix 3 of silica and the polymer soluble in alcohol is formed in the silica-based film 1. The silica-based film 1 further contains hard particles 5. The hard particles 5 is preferably colloidal silica. The hard particles 5 is preferably 10-50 vol.% relative to 100 vol.% of the whole silica-based film 1.SELECTED DRAWING: Figure 1 【課題】釉薬を用いた皮膜に近い意匠性（質感）を実現でき、しかも、皮膜の硬度が釉薬を用いた皮膜に近いシリカ系皮膜を提供する。【解決手段】アルコールに可溶な高分子が含有されたシリカ系皮膜１である。シリカ系皮膜１には、シリカとアルコールに可溶な高分子のハイブリッドマトリックス３が形成されている。シリカ系皮膜１には、更に硬質粒子５が含有されている。硬質粒子５としては、コロイダルシリカが好ましい。シリカ系皮膜１の全体を１００体積％とした場合に、硬質粒子５が１０〜５０体積％含まれていることが好ましい。【選択図】図１
