The present invention provides an adhesive sheet having a resin layer on a substrate or a release material, and at least the surface (α) of the resin layer opposite to the side on which the substrate or the release material is provided is adhesive. At the same time, there is a concave portion on the surface (α), and the standard deviation (σ) of the average luminance value with respect to the surface (α) is 10.0 or more. When the adhesive sheet is attached to the attached body, it can easily remove the generated air storage bubbles, and has excellent gas-removing properties, and also has good adhesive properties. |
