Beschreibung
Zusammenfassung:	The present invention is to improve application of an adhesive sheet by imparting air vent channels to an adhesive surface of the sheet. According to the present invention, air vent channels are formed to have various heights and widths so that the respective air vent channels can be vanished at certain time intervals, thereby facilitating removal of air and increasing an adhesion area to shorten time required for obtaining a designed adhesive force, and the increase of the adhesion area improves smoothness between an adhesive surface and a target surface so that patterns of the air vent channels cannot emerge on a front surface of the sheet.
