<p>Problems: to provide an adhesive sheet in which swelling thereof does not occur since it can let a gas generated from an adherend composed of a porous material go outside of the adhesive sheet, and which exhibits high adhesive force to rough surface. Means for solving the problems: an adhesive sheet which comprises a film substrate layer; a channel breathing layer which has a plurality of convex parts on the surface part of the layer and in which a concave part interposed between said convex parts forms a continuous channel communicating with outside; and a breathing adhesive layer, laminated sequentially in the order.</p> |
