PROBLEM TO BE SOLVED: To prepare an adhesive sheet that has excellent anchoring properties between a base layer and a adhesive layer and is obtained by using a co- extrusion mold which can arbitrarily adjust the strength of the base layer. SOLUTION: This adhesive tape is produced by the co-extrusion of a base layer 1 and an adhesive layer 2 on at least one face of the base layer 1. In one embodiment, the adhesive layer 2 is formed with an adhesive mainly comprising a styrene block copolymer, for example, styrene-isoprene-styrene block copolymer, while the base layer is constituted with a blend of a styrene block copolymer and a styrene resin.
