An anti-vibration rubber composition having a low dynamic magnification and high damping characteristics and a method for producing the same are provided. A rubber composition containing carbon black that has been subjected to a mechanochemical reaction by pulverization with a mill together with a silane coupling agent, the volume specific resistance of the cured body being 1 × 10 6 Ω · cm or more. Yes, the storage elastic modulus at a frequency of 100 Hz and a strain of 0.05% [E '(100 Hz * 0.05%)], and the storage elastic modulus at a frequency of 15 Hz and a strain of 4.5% [E' (15 Hz * 4.5%) ], The vibration damping rubber composition [E ′ (100 Hz * 0.05%) / E ′ (15 Hz * 4.5%)] is 3 or less.
