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