PROBLEM TO BE SOLVED: To provide an adhesive tape which can obtain sufficient adhesiveness to a water-repellent surface and suppresses adhesion of an adhesive agent to a cutter during processing such as cutting and punching.SOLUTION: In an adhesive tape used for adhesion to a water-repellent surface having a pure water contact angle of 140 degrees or more of a packaging material having the water-repellent surface, (1) the adhesive tape has a substrate layer 2 comprising a foam body, and a natural rubber-based adhesive layer 4, (2) the substrate layer 2 has a density of 0.38 g/cmor less and a thickness of 1 mm or less, and (3) the natural rubber-based adhesive layer 4 has (i) a weight per unit area of 35-65 g/m, (ii) a ball number of 10 or more in a ball tack test specified in JIS Z0237, and (iii) a holding power of 100 seconds or more in a holding power test specified in JIS Z0237. |
