To provide an active energy ray-curable composition capable of forming a fine uneven structure having high stain resistance, and to provide a fine uneven structure using the same, and an anti-reflection article.

There is provided an active energy ray-curable composition which comprises: 25 to 75 pts.mass of a polyfunctional monomer (A) having two or more radically polymerizable functional groups in the molecule; 25 to 75 pts.mass of a (meth)acrylate monomer (B) having a siloxane structure; and 0.1 to 5 pts.mass of an active energy ray polymerization initiator based on 100 pts.mass of the polymerizable monomer components.
