To provide a pressure-sensitive adhesive sheet excellent in suitability for ink jet printer, particularly scarcely causing bleeding of printing and satisfying adhesiveness and re-releasability (characteristics bonding pressure-sensitive adhesive surfaces to each other by strong pressure and not bonding these adhesive surfaces to each other even when these adhesive surfaces are pressed to each other after releasing the bond once by hands) as paper for confidential postcards.
The pressure-sensitive adhesive sheet has an adhesive layer on at least either one surface of a base material sheet and the adhesive layer can be bonded by treating the adhesive layers by strong pressure in a state in which the adhesive layers are opposed to each other and the adhesive layer comprises an adhesive containing a natural rubber derivative-based resin as a component, an ink setting agent and an adhesive force control agent and has ≤100°C contact angle after 10 sec under a drop of water of the surface of the adhesive layer.
