    • PROBLEM TO BE SOLVED: To provide a substrate with a transparent coating having a high index of refraction since the transparent coating contains a niobium oxide fine particle, superior in weathering resistance, light resistance, adherence to the substrate, abrasion resistance, scratch strength, pencil hardness and the like, and further creating no interference fringe. SOLUTION: The substrate with the transparent coating comprises the substrate and the transparent coating formed on the substrate, wherein the transparent coating contains a matrix component and the niobium oxide based fine particle having niobium oxide as a main component. The niobium based oxide fine particle is a composite oxide fine particle containing niobium oxide and one or more kinds of oxides selected from the group consisting of oxides of Fe, Ce, Si, Zr, Al, Ti, Sn, Sb, W and Zn. The niobium oxide fine particle has a core-shell structure coating the niobium oxide based fine particle having niobium oxide as the main component or a core particle including other inorganic oxides with one or more kinds of oxides selected from the group consisting of oxide of Nb, Fe, Ce, Si, Zr, Al, Ti, Sn, Sb, W and Zn.
