Provided are: a double-sided adhesive sheet which can exhibit good peeling properties under a constant load even when an adhesive layer therein has relatively high coagulation power; and a double-sided adhesive sheet production method which enables the stable production of the double-sided adhesive sheet. A double-sided adhesive sheet which comprises a base material and adhesive agent layers each formed from a cured product of an adhesive agent composition and respectively provided on both surfaces of the base material, wherein the adhesive agent composition comprises at least a component (A) that is a silyl-terminal polymer and a component (B) that is an adhesiveness-imparting resin, the component (A), i.e., the silyl-terminal polymer, has a specific hydrolysable silyl group at each end of the main chain thereof, the component (B), i.e., the adhesiveness-imparting resin, contains a fully hydrogenated terpenephenol-type resin and is contained in an amount falling within a specified range relative to the amount of the component (A), i.e., the silyl-terminal polymer, and the maximum value of the loss tangent (tanσ) which is determined by the dynamic viscoelasticity measurement (frequency: 1 Hz) of the adhesive agent layer is a value falling within a specified range. |
