To provide a highly damping foam material composition maintaining a high damping property and simultaneously having excellent impact absorption against small loads.
This highly damping foam material composition contains the following component A as a base polymer and further contains the following components B to D. (A) An acrylic rubber having structural units derived from an acrylic monomer having a polar side chain as a main component and further having structural units derived from a cross-linking point monomer having a cross-linking point in a side chain. (B) At least one damping property- imparting agent selected from the group consisting of hindered phenolic compounds, phosphorous ester-based compounds, phosphoric ester-based compounds and nitrogen-containing basic compounds. (C) A cross-linking agent. (D) A foaming agent.
