The purpose of the present invention is to provide a photocurable sheet-type adhesive composition for optical use, which can be used to adhere together a cover glass and a touch panel or a touch panel and a display module, for example, and which has a highly reliable external appearance and storage stability even in high-temperatures and high-humidity. [Solution] The present invention is a photocurable sheet-type adhesive composition for optical use, said composition comprising components (A)-(D): (A) 100 parts by mass of a urethane (meth)acrylate oligomer which has a weight-average molecular weight of 20,000-100,000; (B) 3-70 parts by mass of a phenoxy resin having a glass transition temperature of 50-120 DEG C; (C) 0.1-10 parts by mass of a photopolymerization initiator; and (D) 1-50 parts by mass of a (meth)acrylate monomer comprising 8-30 ether bonded repeating blocks in a molecule, and containing at least one (meth)acryloyl group in a molecule.
