To provide adhesive tape, particularly a masking tape, with a plastic backing layer which has good hand tearability when torn at a desired length, which does not break when the tape is peeled off from the masked section, and which may be peeled off rapidly. The adhesive tape comprises the following features: (1) a tape-like backing layer which includes a tape-like plastic film; (2) an adhesive layer on one principal surface of the backing layer; and (3) an easily tearable section provided in a lengthwise direction at roughly the center with respect to the width of the tape-like backing layer. Preferably, such a tape further includes (4) a light-tacky section or non-tacky section provided in a lengthwise direction on the side of the surface of the adhesive layer which is to be contacted with a substrate to be adhered to, at roughly the center with respect to the width of the adhesive layer facing the easily tearable section.
