PROBLEM TO BE SOLVED: To provide a method of manufacturing an air-permeable adhesive tape, with excellent balance between the adhesive power and the re-adhesiveness while keeping excellent air-permeability. SOLUTION: An adhesive, comprising 6-15 pts.wt. of polyoxyalkylene polymer for 100 pts.wt. of acrylic copolymer, is applied to a sheet for separating at the rate of 20-70 g/m<SP>2</SP>, and aged for 20-60 hours at 40-90°C to form an adhesive layer. Then, the obtained adhesive layer is transcribed and layered on a base material. The adhesive type whose air permeability is 40 sec./300 cm<SP>3</SP>(air) is manufactured by forming the adhesive layer on one side of the base material in the above method. COPYRIGHT: (C)2004,JPO
