Provided is an acrylic resin having photosensitivity for realizing photocurability, and having a superior low-refractive index. This copolymer has an acid value of 20 KOHmg/g or more, and is obtained through ring-opening addition performed on an epoxy group of an epoxy group-containing copolymer (P1) by using an unsaturated carboxylic acid (a-4), and adding a polybasic acid anhydride (a-5) to a hydroxyl group generated through ring-opening of the epoxy group. The epoxy group-containing copolymer (P1) contains: at least one structural unit selected from the group consisting of structural units derived from polymerizable monomers (a-1A) having a bridged cyclic hydrocarbon group having 10-20 carbon atoms, and structural units derived from polymerizable monomers (a-1B) represented by chemical formula (1); a structural unit derived from a fluorine-containing (meth)acrylate (a-2) represented by chemical formula (2); and a structural unit derived from an epoxy group-containing (meth)acrylate (a-3).
