PROBLEM TO BE SOLVED: To provide an active energy ray-curable optical adhesive composition, from which a film having a low dielectric constant and having excellent transparency under a high temperature and high humidity condition can be obtained; and to provide an optical adhesive sheet, an image display unit, an output/input unit, and a method for producing an adhesive layer.SOLUTION: The active energy ray-curable optical adhesive composition is a solventless composition comprising (A) Component: a hydrogenated conjugated diene-based polymer containing a hydrogenated conjugated diene-based polymer portion and a reactive double bond, (B) Component: a monomer having a linear or branched alkyl group having 8 or more but 18 or less carbon atoms, and (C) Component: a monomer having a hydroxyl group and/or a nitrogen atom-containing group. A weight average molecular weight of the (A) Component is 10,000 or more but 100,000 or less, and a content of the (B) Component relative to a total content of the (A) Component, the (B) Component, and the (C) Component is 5 mass% or more but 20 mass% or less. |
