Abstract

An adhesive sheet comprises a film substrate layer, a channel breathing layer and a breathing adhesive layer. The channel breathing layer has a plurality of convex parts and a concave part interposed between the convex parts that forms a channel communicating with the outside. When the adhesive sheet is applied to an adherend, gas generated from the adherend passes through the channel and swelling of the adhesive sheet is avoided.
