Disclosed herein is a pressure sensitive adhesive tape or sheet comprising a base layer (substrate) formed of a polyolefin resin and a pressure sensitive adhesive layer laminated on one side of the base layer, optionally, through an intermediate layer. The pressure sensitive adhesive tape or sheet is characterized in that the back surface of the base layer has been applied with shearing force so as to subject it to a surface treatment and is improved in unwinding ability, namely, is capable of rerolling with small force when it is wound into a roll.
