Provided is a photocationically polymerizable adhesive composition with good adhesiveness and durability. The adhesive composition comprises 75 to 99.8 parts by weight of (a) at least one compound selected from the group consisting of aliphatic epoxy, alicyclic epoxy, oxetane and vinyl ether compounds, 0.1 to 5 parts by weight of (b) a titanate coupling agent, and 0.1 to 20 parts by weight of (c) a photopolymerization initiator, the sum of the weights of (a), (b) and (c) being 100 parts by weight. |
