Abstract
A medical dressing includes: a lower support film; a release film; and an adhesive sheet part (110) for application, which is placed on the release film (200) and is attached to the skin, wherein the release film (200) consists of a release film part (210) for fixing and a separable release film part (220) to be separated therefrom by a cutting line (211) formed on the release film part (210) for fixing, so that a predetermined region of the separable release film part is positioned to overlap with the bottom surface of the adhesive sheet part (110), thereby allowing, during separation of the separable release film part (220) from the release film part (210) for fixing, separation together with the adhesive sheet part (110) for application, and the area of the separable release film part (220), which overlaps with the bottom surface of the adhesive sheet part (110), is relatively smaller than the area of the separable release film part, which does not overlap with the adhesive sheet part (110).
