(1) A polyamide resin composition comprising, relative to 100 parts by volume of a polyamide resin, 50 to less than 100 parts by volume of flake graphite, 5 to 40 parts by volume of carbon fibers, and 0.1 to 5 parts by volume of a polyhydric alcohol;
(2) 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 the dicarboxylic acid units of the polyamide resin are oxalic acid in an amount of 70 mol% or more, based on the total dicarboxylic acid units; or
(3) a polyamide resin composition comprising a polyamide resin and metal oxide particles, wherein the polyamide resin composition contains the metal oxide particles in an amount of 70 to 85% by mass, based on the mass of the polyamide resin composition, 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.
