PROBLEM TO BE SOLVED: To provide a pressure sensitive adhesive sheet which does not change the external appearance such as yellowing, maintains sufficient adhesion, neither has a dry spot of the pressure sensitive adhesive sheet nor peels off even when placed in a high temperature high humidity environment for a long period of time after being applied to an adherend, particularly a glass sheet, and is easy to release again even with time without leaving the paste to stain the glass surface on releasing, and can simultaneously have the effect of preventing glass from flying in all directions, and a pressure sensitive adhesive composition to be used in the pressure sensitive adhesive sheet. SOLUTION: The pressure sensitive adhesive composition comprises (A) 100 pts.wt. acrylic copolymer having (a) 1.3-10 wt.% hydroxyl group-containing vinyl monomer and (b) 0.05-1.0 wt.% carboxyl group-containing vinyl monomer as the constituting components, simultaneously, with≥50 wt.% total constituting components being an acrylic monomer and (B) 0.01-1.0 pt.wt. ketimine silane compound.
