Summary:A silicone rubber sponge composition, a silicone rubber sponge, and a process for production thereof. The silicone rubber sponge composition comprises (A) 100 parts by weight organopolysiloxane gum described by average structural unit RaSiO(4-a)/2, where R is a monovalent hydrocarbon group or haloalkyl and a is 1.8 to 2.3 and having a viscosity at 25 DEG C of 1,000,000 mPa . s or above, (B) 1 to 400 parts by weight inorganic filler, (C) 0.01 to 50 parts by weight hollow thermoplastic resin particles, (D) 0.01 to 10 parts by weight a water-in-oil emulsion with silicone oil an oil phase, and (E) a curing agent in an amount sufficient to cure the composition.
