  • Patent number: 9177692
    Abstract: A polyamide resin composition comprising defined amounts of flake graphite, carbon fibers, and polyhydric alcohol. A polyamide resin composition comprising a polyamide resin and, as a property imparting component, at least one member selected from the group consisting of a metal oxide, a nitrogen compound, and a silicon compound, wherein a defined amount of the dicarboxylic acid units of the polyamide resin are oxalic acid. A polyamide resin composition comprising a polyamide resin and a defined amount of metal oxide particles, wherein the metal oxide particles contain those having a particle size of 70 ?m or more in an amount of 10 to 50% by mass and those having a particle size of 20 ?m or less in an amount of 1 to 50% by mass, based on the total mass of the metal oxide particles.
