A curable fluorosilicone composition is provided. The curable fluorosilicone composition comprises: (A) an organopolysiloxane having at least two alkenyl groups and at least one fluoroalkyl group in a molecule; (B) an organopolysiloxane having at least two silicon atom-bonded hydrogen atoms and at least one fluoroalkyl group in a molecule; (C) a platinum group metal-based catalyst for hydrosilylation reaction; and (D) a hydrosilylation reaction inhibitor having an aliphatic unsaturated bond. Component (C) is an encapsulation type catalyst having an acrylic resin as a wall material. The platinum group metals in component (C) relative to the composition are 0.1 to 100 ppm. The molar ratio of the aliphatic unsaturated bonds in component (D) relative to the platinum group metals in component (C) is 1 to 100. The curable fluorosilicone composition has favorable curability and a sufficiently pot life at room temperature.
