A pressure sensitive adhesive tape for skin, including a stretchable base material having good moisture permeability and a pressure sensitive adhesive layer formed on at least one side of the base material, wherein the adhesive tape has features that (a) the conformability to a stretchable film is at most 4.2 times as much as the stress of the stretchable film at 15% elongation, (b) the water-vapor transmission rate is at least 500 g/m<2>.24 h, and (c) the adhesive strength to bakelite is at most 1.5 N/15 mm, and a base material of a pressure sensitive adhesive tape for skin, including a microporous film formed from a resin composition containing a polyolefin resin and an inorganic filler, and having features that (1) the thickness is 40 to 200 mu m, (2) the average pore size is 0.02 to 10 mu m, (3) the air permeability is 10 to 400 sec/100 cc, (4) the water-vapor transmission rate is 1,000 to 20,000 g/ m<2>.24 h, and (5) the stresses at 15% elongation in the machine direction and transverse direction is both 0.5 to 15 N/15 mm. |
