Abstract: PROBLEM TO BE SOLVED: To provide a silicone rubber sponge having a high open cell ratio of ≥ 15% and having fine cells uniformly, and to provide a method for manufacturing the silicone rubber sponge. SOLUTION: The silicone rubber sponge is prepared by subjecting a composition containing at least (A) a silicone rubber compound which is a mixture containing organopolysiloxane expressed by an average composition formula (1) R 1 nSiO (4-n)/2 and reinforcement silica and in which a moisture content prior to crosslinking is ≥0.5%, (B) at least an organic azo foaming agent or sodium hydrogencarbonate foaming agent, and (C) a non-acyl-based organic peroxide of ≥150°C in 1-minute half-life temperature to ordinary temperature thermocrosslinking, foaming and curing to thereby uniformly form fine cells of ≥l5% continuous cell rate.
