PROBLEM TO BE SOLVED: To provide a novel antistatic agent capable of providing a cured film having excellent antistatic property, transparency and moisture heat resistance. SOLUTION: The structural unit (a1) derived from a vinyl monomer having a quaternary ammonium salt structure, a ring-opening weight adduct of a hydroxyl group-containing vinyl monomer and a lactone, and a weight average molecular weight of 1,000 to 10,000. A structural unit derived from a vinyl monomer (a2), a structural unit derived from a vinyl monomer containing an alkyl ester group having 1 to 18 carbon atoms (a3), and a polyazo compound having a polyoxyethylene structure and / or a polyoxyethylene structure. An antistatic agent for an active energy ray-curable resin composition containing a polymer (A) containing a constituent unit (a4) derived from a polyperoxide compound having.
