The present invention provides an adhesive sheet having a resin portion (X) on a base material or a release material, containing a hydrocarbon resin having a carbon atom in the main chain of a structural unit as a main component, and a resin portion (X) containing a silicon dioxide-containing resin. The resin layer of the particle portion (Y) formed by the particles of the particles is at least adhesive to the surface (α) of the resin layer on the side opposite to the side on which the substrate or the release material is provided. The resin layer is, An energy dispersive X-ray analyzer is used to form a multilayer structure having a layer (Xα) and a layer (Y1) sequentially in a thickness direction from the surface (α) side, and the surface (α) side of the resin layer is used. In the thickness direction, when measuring the intensity ratio [Si / C] of the peak intensity (Si) generated by silicon atoms to the peak intensity (C) generated by carbon atoms, the intensity ratio in the layer (Xα) is less than 0.10 The layer (Y1) has an intensity ratio of 0.10 or more, and the surface (α) has recesses of an unspecified shape. |
