This invention relates to a resin composition comprising a resin component in an amount of 100 parts by weight, thermally expandable graphite in an amount of 3 to 300 parts by weight, and an inorganic filler in an amount of 2 to 200 parts by weight, wherein the expansion starting temperature of the thermally expandable graphite is lower than the decomposition starting temperature of the resin component. |
