A plaster comprising the film layer which is composed of a film having 0.5 to 4.9 µm thickness, 8 to 85 g/mm strengths, respectively in the two directions intersecting substantially at right angle, 30 to 150% elongations, re-spectively in the two directions intersecting at right angle, and 1.0 to 5.0 ratio between the two direction elon-gations (wherein the smaller elongation is used as the denominator, when the ratios of the elongations in the 2 directions are different) and an adhesive layer (a) which contains a transdermally absorbable drug and is laminated on one surface of said film layer in 2 to 60 µ m thickness enables transdermal absorption of a clinically effective amount of a drug with skin rashes reduced. Additionally, a backing sheet may be preferably provided, for example, the plaster made of said film layer (3) and said adhesive layer (a) (4) is press-bonded via an adhesive layer (b) (2) to a backing sheet (1) and a release film (5) to give a plaster of improved handleability. |
