Abstract: A sealing sheet is provided which is used for sealing of a semiconductor chip embedded in a substrate or a semiconductor chip on a pressure sensitive adhesive sheet in a method for producing a semiconductor device. The method includes a treatment step using an alkaline solution. The sealing sheet includes at least an adhesive layer having curability. The adhesive layer is formed of an adhesive composition that contains a thermoset resin, a thermoplastic resin, and an inorganic filler. The inorganic filler is surface-treated with a surface treatment agent having a minimum coverage area of 550 m2/g or more and 1,500 m2/g or less. The sealing sheet is less likely to cause the inorganic filler to escape from a cured layer 11′.
