    • There are disclosed a silicone rubber based pressure sensitive adhesive sheet comprising a transparent substrate film and a silicone rubber layer which is formed by coating the surface of the transparent substrate film with silicone rubber in an amount of 5 to 100 g/m2 (after drying) containing addition type organopolysiloxane composed of organopolysiloxane having a siloxane bond as a principal skeleton and bearing an alkenyl group and of organohydrogenpolysiloxane, the silicone rubber further containing 0.01 to 3.0 parts by mass of a platinum catalyst based on 100 parts by mass of the addition type organopolysiloxane, and then by curing the resultant coating, and which has adhesion for float glass in accordance with JIS Z 0237 being in the range of 10 to 1000 mN/25 mm, holding power (load of one kg) of at least 24 hours and a 100% modulus in the range of 0.3 to 1.5 MPa. The resultant silicone rubber based pressure sensitive adhesive sheet is imparted with strong holding power, sufficient adhesiveness to the substrate film and sufficient removability from an adherend enabling repeated sticking even if an additive such as an adhesion improving agent is not blended, and at the same time which makes it possible to use as a releasing film, an inexpensive film not subjected to a releasing treatment.
