PROBLEM TO BE SOLVED: To provide a photocuring adhesive which is of the one-pack curable type, easy to handle, free from discharge of a solvent or the like, curable in a short period of time, high in bonding strength and excellent in moisture resistance. SOLUTION: This photocuring adhesive composition comprises (A) 10-70 pts.wt. urethane polymer having a polycarbonate doil having two or more (meth) acryloxy groups in the molecule as the main chain skeleton, (B) 30-90 pts.wt. monofunctional (meth)acrylate, (C) 0-40 pts.wt. polyfunctional (meth)acrylate, and (D) 0.01-5 pts.wt. [provided that the sum of components (A)-(C) is 100 pts.wt.] photopolymerization initiator. An optical member is obtained by laminating sheet lenses with this adhesive composition.
