PROBLEM TO BE SOLVED: To provide an active energy ray-curable self-adhesive composition giving no reverse effect on properties even in curing. SOLUTION: Provided are an active energy ray-curable self-adhesive composition comprising an ingredient (A1): a polyurethane being prepared by reacting (a) a hydroxy-containing benzoyl compound, (b) a polyisocyanate compound, and (c) a compound prepared by reacting a compound having a hydroxy group and a vinyl group, and an ingredient (B): an active energy ray-polymerizable monomer giving a polymer having≤20°C glass transition temperature by polymerization; and an active energy ray-curable self-adhesive composition comprising an ingredient (A2): a polyurethane having 1,000-100,000 weight-average molecular weight and 2-4 average number of crosslinked positions per a molecule and being prepared by reacting (a) a hydroxy group-containing benzoyl compound, (b) a polyisocyanate compound and (c) a compound prepared by reacting a compound having a hydroxy group and a vinyl group, and an ingredient (C): an active energy ray-curable monomer mixture giving a copolymer having≤100°C glass transition temperature by copolymerization.
