摘要： Provided is a masking tape for a shot peening process, including: a substrate having a first surface and a second surface; and a pressure-sensitive adhesive layer disposed on the first surface of the substrate. The masking tape has a breaking strength of 55 N/15 mm or more and exhibits an impact absorption rate of 20% or more in a falling ball impact test. Further, the masking tape has a displacement distance of 2 mm or less after 1 h from an initial position in a holding power test at 40° C. which is performed by applying a load of 500 g.
