An adhesive film mainly has a body which has a printed pattern layer on one side and a smooth layer on another side. The smooth layer is coated with an adhesive layer. The adhesive layer is bonded to a release paper on one side that has a concave and convex layer. When the release paper is peeled off, the adhesive layer has a convex and concave layer formed on one side due to bonding with the concave and convex layer of the release paper. The convex and concave layer has a plurality of air passages formed thereon. Thus during flat bonding process air is discharged through the air passages, and bonding result is flat and neat.
