A1

Disclosed is an adhesive sheet which is obtained by co-extruding an adhesive layer and a layer (a releasing layer) that is releasable from the adhesive layer. The adhesive sheet is characterized in that the base polymer of the adhesive layer is an acrylic polymer. Specifically disclosed is an adhesive sheet (10) which is obtained by co-extruding an adhesive layer (12) that contains an acrylic block copolymer as the base polymer, an RA layer (14) that is laminated on a first surface (12A) of the adhesive layer (12), and an RB layer (16) that is laminated on a second surface (12B) of the adhesive layer (12). Both of the RA layer (14) and the RB layer (16) are releasable from the adhesive layer (12).
