PROBLEM TO BE SOLVED: To stabilize adhesion at the time of sweating, etc., and to reduce a pain, etc., at the time of releasing by setting the follow-up property, a water vapor transmission ratio, counter-bakelite adhesion respectively to a specific value. SOLUTION: As a supporter of an adhesive tape for sticking a skin, an extensible film whose extensible film follow-up property is not smaller than the 4.2 fold of film stress at the time of extending by 15% is used. In addition, its water vapor transmission ratio is not smaller than 500 g/m2 24 h and the counter bakelite adhesion is not larger than 1.5N/15 mm. As this extensible supporter, a polyurethane film, a polyurethane nonwoven fabric, etc., can be used. Its thickness is desirably about 40 to 200μm in usual. For example, the copolymer of isononyeacrylate/methoxynonaethyleneglycol acrylate/nonaethylene glycol methacrylate, e.g. is used as the adhesive and a polyolefin type permeable film is formed as a supporter. Thus adhesion is stabilized.
