PROBLEM TO BE SOLVED: To provide an adhesive tape for protecting a surface of a semiconductor wafer, which allows a thin film wafer having a thickness of ≤100 μm to be formed even when a rear surface of the semiconductor wafer is ground with the adhesive tape stuck to the semiconductor wafer. SOLUTION: The adhesive tape for protecting the surface of a semiconductor wafer has: a substrate resin film; and a direct adhesive layer on the substrate resin film through an intermediate resin layer in which base resin components containing an acrylic copolymer and/or polyurethane acrylate copolymer are cross-linked. The repulsion coefficient γ obtained by dividing repulsion force α per unit width, which is found from the load of loop stiffness obtained by measuring the adhesive tape for protecting the surface of the semiconductor wafer under a specific condition, by the square of the thickness β of a substrate is 100 mN/mm 3 or more, the repulsion force α is 13 mN/mm or less, and the difference between tensile fracture elongations in a longitudinal direction and a lateral direction is 35% or less.
