PROBLEM TO BE SOLVED: To provide a method for producing a tacky adhesive sheet, by which a tacky adhesive sheet can be produced at a low cost by a winding system in current equipment with fewer air bubbles entangled during production even when a tacky adhesive layer comprises a core material impregnated with a tacky adhesive.SOLUTION: The method includes: (1) a first laminate 31A step of laminating a core material on the release layer face of a first release sheet 21A, applying the tacky adhesive 13 to the surface of the core 15 and winding up the sheet; (2) a second laminate 31B step of applying the tacky adhesive 13 to the release layer face of a second release sheet 21B and winding up the sheet; and (3) a tacky adhesive sheet 1 step of laminating the core material 15 face of the first laminate 21A and the tacky adhesive 13 face of the second laminate 31B, and pressurizing and winding up the sheet. The tacky adhesive sheet comprises the first release sheet 21A, the tacky adhesive layer 11 comprising the core material impregnated with the tacky adhesive, and the second release sheet 21B, and has both of the tackiness and the adhesiveness, wherein the tacky adhesive 13 contains an acrylic resin, an epoxy resin and a curing agent. |
