PROBLEM TO BE SOLVED: To efficiently provide a foam which has high rate of continuous foams, flexibility, recovering property and size stability without using a special manufacturing process nor a device. SOLUTION: The composition for a silicone rubber foam with interconnected air bubbles comprises: (A) 100 parts wt. of a mixture containing 100 parts wt. of (A-1), a polyorganosiloxane containing an alkenyl group, and 5-100 parts wt. of (A-2), a filler; (B) a vulcanization agent for an organic peroxide in an amount which is sufficient enough to cure a rubber and makes the scorch time (time for initial vulcanization) 10 minute or more at a decomposition temperature of heat decomposable foaming agent in a state where a heat decomposable foaming agent (C) and an interconnecting agent are incorporated; (C) 0.1-10 parts wt. of a heat decomposable agent; and (D) 0.01-10 parts wt. of an interconnecting agent selected from a nonionic surfactant and a silane coupling agent having an epoxy group.
