There is provided a photo-curable composition that shows the suppression of a residual film formation and a high adhesion thereof to a substrate in a process for forming a three-dimensional pattern by a photo-imprinting method. A photo-curable composition for forming a three-dimensional pattern by a photo-imprinting method, comprises a monomer having a photopolymerizable group; an inorganic fine particle to which a dispersant is added; and a photopolymerization initiator. It is preferred that the inorganic fine particle (e.g., silica) has an average particle diameter of 1 to 1,000 nm, and the dispersant is a silane coupling agent, particularly a silane coupling agent containing an organic group having a carbon-carbon unsaturated bond or an organic group having an epoxy group.
