摘要 |
The present invention relates to a pressure sensitive adhesive sheet 1 comprising a base material 11 and a pressure sensitive adhesive layer 12 wherein a plurality of through holes 2 passing through one face of the pressure sensitive adhesive sheet 1 to the other face are formed. The hole diameter of the through holes 2 is 0.1 to 300 µm and the hole density is 30 to 50,000/100 cm 2 . It is preferable to form the through holes 2 using a laser beam machining. According the pressure sensitive adhesive sheet 1, an air trapping or a blister can be prevented or removed without disfiguring the pressure sensitive adhesive sheet and while securing a sufficient adhesive strength. |
