PROBLEM TO BE SOLVED: To provide a silicone rubber adhesive sheet having sufficient holding power and sufficient removability enabling repeated sticking even if an additive such as an adhesion improving agent is not blended and capable of using an untreated film as a release film. SOLUTION: The silicone rubber based adhesive sheet is obtained by providing a silicone rubber layer formed by coating the surface of the transparent substrate film with a silicone rubber in an amount of 5 to 100 g/m<SP>2</SP>(after drying) containing an addition type organopolysiloxane composed of an organopolysiloxane having a siloxane bond as a principal skeleton and bearing an alkenyl group and an organohydrogenpolysiloxane and further containing a platinum catalyst in an amount of 0.01-3.0 pts. mass, based on 100 pts. mass the addition type organopolysiloxane and then 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 1 kg) of at least 24 hours and a 100% modulus in the range of 0.3 to 1.5 MPa on the surface of the transparent substrate film.
