A patch having a layer structure that a pressure sensitive adhesive layer is provided on one surface of a base layer, wherein the base layer is an elastomer film having a thickness of 1 to 10 µm, the thickness of the pressure sensitive adhesive layer is 1 to 15 µm, the total thickness of the base layer and the pressure sensitive adhesive layer is within a range of from 2 to 20 µm, the 10% tensile load of the patch in each of machine and transverse directions is 0.01 to 1.2 N/10 mm, assuming that the 10% tensile load value of the patch in the machine direction is X (N/10 mm), the thickness value of the patch is Y (µm), and the thickness value of the base layer is Z (µm), the patch satisfies the relationship of XY = 0.02 to 15, or XZ = 0.01 to 7, and the pressure sensitive adhesive layer exhibits adhesive strength of 0.1 N/10 mm or more. |
