PROBLEM TO BE SOLVED: To provide an inexpensive easily producible pressure-sensitive adhesive tape which is applied to the scaffold of a building site, can contribute to the safety and efficiency of a work, is ready for the drainage of e.g. rainwater and has excellent antislip effect. SOLUTION: This sheet is prepared by laminating a pressure-sensitive adhesive layer on the back of a support on which many embosses are formed to form parallel lines. The support is an unoriented film of a polyolefin resin. The height of each of the embosses formed on the surface of the support is 20-500μm, and the distance between adjoining embosses is 0.4-10mm. The thickness of the support coinciding with the groove and being the thinnest is 10-100μm, and the thickness of the pressure-sensitive adhesive layer laminated on the back of the support is 25μm or above.
