A paste-like thermally foaming filler contains 2 to 20 parts by weight of an uncrosslinked synthetic rubber, 5 to 30 parts by weight of a partially crosslinked rubber, 0.1 to 5 parts by weight of a quinone-based vulcanizing agent, 0.2 to 1.5 parts by weight of thermally expandable balloons, 1 to 10 parts by weight of a thermoplastic resin, 20 to 50 parts by weight of a plasticizer, 15 to 50 parts by weight of an inorganic filler, and 2 to 15 parts by weight of a chemical foaming agent. The paste-like thermally foaming filler exhibits high foaming capability even at low temperatures. |
