Abstract: A simple adhesive tape cutter and marker of the present invention implements the marker on an adhesive tape roll, and is primarily configured to comprise the marker affixed to a side edge of a reel of the adhesive tape roll. Length of the marker is such to enable encircling any position around a largest periphery of the adhesive tape, and a cutting member is configured on the marker. The cutting portion of the marker is employed to cut the adhesive tape; moreover the marker can be placed below a cutting position of the adhesive tape, the adhesive tape covering the marker thereat. Thus, next time the adhesive tape is to be cut, the marker directly indicates a draw-end of the adhesive tape, and thereby realizes easy lifting up of the draw-end.
