An anti-reflection film which includes an inorganic anti-reflection layer including a silicon dioxide-based inorganic layer and having a monolayer structure or plural-layer structure, and a stain-resistant layer provided as a surface layer, is provided. The stain-resistant layer is composed of a cured product of a particular fluorine-containing silazane compound. An optical member having the anti-reflection film on a substrate, such as an optical element, is also provided.
