A medical pressure sensitive adhesive tape includes a base material and a pressure sensitive adhesive layer formed on at least one side of the base material. The medical pressure sensitive adhesive tape is greatly lightened in skin irritation and has the following characteristics: (a) the stress at 5% elongation being within a range of 0.1 to 8.0 N/24 mm as measured at a temperature of 23 DEG C and an extension rate of 100 mm/min; (b) the viscosity (unit: Pa.s) of a pressure sensitive adhesive being within a range of 5.0 to 6.7 in terms of logarithm as determined from an initial slippage under shear load; and (c) the water-vapor transmission rate being within a range of 800 to 8,000 g/m .24 hr as measured at a temperature of 40 DEG C and a relative humidity of 90%.
