The invention discloses a silicone composition and a pressure sensitive adhesive film having a pressure sensitive adhesive layer made from the composition. The pressure sensitive adhesive film comprising a substrate film and a pressure sensitive adhesive layer formed on a surface of the substrate film, said pressure sensitive adhesive layer being made from a silicone composition comprising: a diorganopolysiloxane having at least two alkenyl groups in a molecule and having a viscosity at 25 DEG C of from 10,000 to 1,000,000 mPa.s; (B) a diorganopolysiloxane having at least one alkenyl group in a molecule, and being a raw rubberlike at 25 DEG C or having a viscosity at 25 DEG C of more than 1,000,000 mPa-s, in an amount of not more than 10 mass % based on a mass of the composition; (C) an organopolysiloxane resin represented by the following average unit formula: (R1 3SIO1/2)x (Si04/2)1.0, wherein each R1 represents a halogen-substituted or unsubstituted monovalent hydrocarbon group free from an alkenyl group and x is a number from 0.5 to 1.0; (D) an organohydrogenpolysiloxane having at least two silicon-bonded hydrogen atoms in a molecule; (E) silica fine powder; and (F) a hydrosilylation catalyst.
