The present invention provides a photocurable pressure-sensitive adhesive composition which has sufficient adhesion before being irradiated with light, and after being irradiated with light, keeps a sufficient pot life and has a short cure-completion time at a room temperature. A cured product produced from the composition has high adhesion force to adherends difficult to be attached, and excellent durability. The photocurable pressure-sensitive adhesive composition comprises a crosslinking compound (A) that is crosslinkable by the action of a base, a photobase generator (B) which becomes active upon light irradiation to generate a base, and a tackifying component (C).
