A pressure-sensitive adhesive composition having good durability when bonded as a pressure-sensitive adhesive layer to the surface of an optical member, a pressure-sensitive adhesive layer containing the same, and an optical member with a pressure-sensitive adhesive layer including the pressure-sensitive adhesive layer are provided. . A (meth) acrylic resin (A) in which the content of a structural unit derived from a (meth) acrylic monomer having a hydroxyl group is 3.5% by weight or less and the glass transition temperature is −25 ° C. or less. ) At least 1 selected from 100 parts by weight, 0.3 to 1 part by weight of an aromatic isocyanate crosslinking agent (B), and an organic acid salt (C-1) and a compound (C-2) containing an alkyleneoxy group When the organic acid salt (C-1) is contained, the content is 0.0001 to 5 parts by weight, and the compound (C-2) containing an alkyleneoxy group is contained. When it contains, the adhesive composition whose content is 0.1-5 weight part, the adhesive layer containing it, and an optical member with an adhesive layer provided with the said adhesive layer are provided.
