Provided is a silicone rubber composition that has excellent storage stability and an improved post-curing compression set, and a silicone rubber cross-linked body made from the silicone rubber composition. A silicone rubber composition contains (a) an organopolysiloxane, (b) a cross-linking agent, and (c) a microcapsule type catalyst that is made from resin microparticles encapsulating a cross-linking catalyst, wherein the resin of (c) is one of a thermosetting resin that is thermally cured in the presence of the cross-linking catalyst and a thermosetting resin that is thermally cured in the absence of the cross-linking catalyst.
