PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition having low peeling characteristics and good constant loadability, a pressure-sensitive adhesive sheet using such a pressure-sensitive adhesive composition, and a method for producing a pressure-sensitive adhesive sheet. A pressure-sensitive adhesive composition comprising at least a terminal silyl group polymer as a component (A), a (meth) acrylic acid ester polymer as a component (B), and a tackifying resin as a component (C). The terminal silyl group polymer as the component (A) has a polyoxyalkylene structure in the main chain, and has a urethane bond and / or a urea bond in a part of the main chain or a side chain. Furthermore, the (meth) acrylic acid ester polymer as the component (B) has a predetermined hydrolyzable silyl group at both ends of the main chain, and the carboxyl group-containing (meth) acrylic acid An ester copolymer and a non-functional (meth) acrylic acid ester polymer are included.
