PROBLEM TO BE SOLVED: To provide a highly damping rubber composition which maintains rigidity, imparts a high damping property, has high stiffness, and simultaneously has excellent breaking strength and processability. SOLUTION: This highly damping rubber (composition) 2 used in a seismic isolation structure 1 and comprising 100 pts. wt. of a rubber component comprising a dienic rubber, 40 to 95 pts. wt. of carbon black having a cetyltrimethylammonium bromide adsorption specific surface area (CTAB) of 100 to 170 m<SP>2</SP>/g, and 5 to 50 pts. wt. of a resin, is characterized in that≥10 wt.% of the amount of the compounded resin comprises an aromatic oligomer containing a di- or tri-cyclic heterocyclic aromatic component containing at least one of nitrogen or sulfur in the ring-forming components in an amount of≥60 wt.%.
