[Problem]To provide: a curable organopolysiloxane composition, which is a composition that has relatively low viscosity before curing, can be easily processed into a film shape, and excellent mechanical strength (specifically, tensile strength, tear strength, elongation, and the like) when used as a dielectric layer in a transducer, and an application thereof.[Resolution Means]A curable organopolysiloxane composition, containing (A1, A2) a combination of chain organopolysiloxanes having an alkenyl group only on an end of a molecular chain, and a degree of polymerization within a range of 50 to 550 and a range of 600 to 1000, (B) hydrophobically treated reinforcing silica, (C) a siloxane resin containing an alkenyl group, (D) organohydrogenpolysiloxane, and (E) a catalyst, where (A1)/(A2) is within a range of 0.45 to 1.30, the sum of component (B) and component (C) is within a range of 10 to 25 mass% of the entire composition, and the SiH/Vi ratio an amount of 1.0 to 2.5 mols, and an application thereof. |
