摘要： A double-sided pressure-sensitive adhesive tape includes a nonwoven fabric substrate and pressure-sensitive adhesive layers present on both sides of the substrate, in which the nonwoven fabric substrate contains at least Manila hemp, has a thickness of 18 μm or less, and has a tensile strength in a machine direction of 4 N/15 mm or more. The double-sided pressure-sensitive adhesive tape is thin and is effective for the reduction in size and thickness of products to be fixed through the tape. The tape has a high strength in the machine direction and does not break during production and processing processes. In addition, the tape has a nonwoven fabric substrate and thereby excels also in punching quality. The tape is therefore particularly useful as a double-sided pressure-sensitive adhesive tape for fixing a wiring circuit board.
