Abstract
This invention provides a PSA sheet with which degradation of the appearance after its application is efficiently prevented while showing uniform adhesive properties over the entire sheet with greater ease of application. The PSA sheet provided by this invention is an air-impermeable PSA sheet having an adhesive surface. The PSA sheet comprises a PSA layer forming the adhesive surface. In the adhesive surface, at least one groove is formed. The groove runs in a wavy shape in the adhesive surface.
