CA 2542688

The present invention provides an adhesive preparation superior in adhesion property, which does not peel off or fall off easily and which can be adhered for a long time. An adhesive preparation 10 has a support 1 made of a cloth, and a pressure sensitive adhesive layer 3 formed on one surface of the support 1, which contains a pressure sensitive adhesive and a drug. The ratio (CW/AW) of a mass (CW) per unit area of the support 1 and a mass (AW) per unit area of the pressure sensitive adhesive layer 3 is 1.0 - 5.0, an adhesive layer-free surface of the support 1 has a static friction coefficient of 0.25 - 0.75, and a 20% modulus (AM) in one direction of the adhesive preparation 10 and a 20% modulus (EM) in the direction perpendicular to that direction are each 0.5 - 1.5 N/cm, and the ratio thereof (AM/EM) is 0.5 - 2Ø
