To provide a double-sided adhesive sheet having excellent adhesiveness, especially hot-water resistant adhesiveness between a silicone adhesive layer and a substrate film, the releasing force between the silicone adhesive layer and a separate film being moderately controlled, a method for efficiently and economically producing the double-sided adhesive sheet, and a method for a suitable use of the double-sided adhesive sheet.
Disclosed is a double-sided adhesive sheet including (A) a polyester film, (B) a releasing layer, (C) an adhesive layer containing a crosslinked silicone compound having a polydimethylsiloxane skeleton, (D) a layer for improving hot-water resistant adhesiveness, (E) a polyester-based film, (D') a layer for improving hot-water resistant adhesiveness, (C') an adhesive layer containing a crosslinked silicone compound having a polydimethylsiloxane skeleton, (B') a releasing layer and (A') a polyester film, they being laminated in the order, wherein both the peel strength between the releasing layer (B) and the adhesive layer (C) and that between the releasing layer (B') and the adhesive layer (C') determined by a specifically defined method are 0.03-1.0 N/20 mm.
