PROBLEM TO BE SOLVED: To obtain the subject adhesive tape capable of readily cutting off with finger tips and excellent in weather resistance and strength by providing a prescribed groove on the surface of the tape. SOLUTION: In this tape obtained by providing an adhesive mass layer on either one surface of a polyolefin-based resin film containing a polyolefin-based resin and one or more kinds of an ultraviolet light absorbent, a hindered amine- based compound and an organophosphoric metal salt of formula I and/or II (M is Zn, Ca or the like; R1 to R5 are each a 1-22C alkyl or the like) in an amount of 0.1-3 pts.wt. based on polyolefin-based resin, plural linear grooves having V-shaped cross section are formed parallel to width direction of the tape and angles A and B at which opposite two inclined surfaces of V-shaped groove cross section form with the tape face or angles A and B at which tangent lines drawn at a position of 1/2 based on groove depth to two U-shaped opposed curved surfaces form with the tape face satisfy the formula III to VI and the depth of the groove is 1/10 to 1/2 based on tape thickness and pitch of the groove is 100-300μm. Furthermore, the adhesive mass layer preferably contains a re-releasable adhesive mass.
