PROBLEM TO BE SOLVED: To provide a self-adhesive tape or sheet excellent in reworking property and operability in correction of a pasted position, and its manufacturing method. SOLUTION: The self-adhesive tape or sheet comprises a support and, formed on at least one face thereof, a self-adhesive layer, where the surface of the self-adhesive layer on at least one face of the support partially has a fibrous projecting structure part. Preferably, the fibrous projecting structure part comprises a napped fiber part having a structure where the fiber rises from the surface of the self-adhesive layer. The self-adhesive tape or sheet is useful as one for pasting a flooring material. The manufacturing method of the self-adhesive tape or sheet comprises flocking the surface of the self-adhesive layer on at least one face of the support by means of a flocking processing method thereby to partially form the fibrous projecting structure part on the surface of the self-adhesive layer.
