PROBLEM TO BE SOLVED: To provide a polyamide resin composition made to have sufficient high molecular weight, wide in moldable temperature width estimated from the difference between melting point and thermal decomposition temperature, superior in melting moldability, also superior in conductibility, while being low in water absorbability; furthermore, superior in chemical resistance, hydrolysis properties and the like, compared with conventional aliphatic polyamide resins. SOLUTION: In the polyamide resin composition, a polyamide resin, of which the dicarboxylic acid component includes oxalic acid and the diamine component is composed of 1,9-nonanediamine and 2-methyl-1,8-octanediamine with the molar ratio between 1,9-nonanediamine and 2-methyl-1,8-octanediamine being from 1:99 to 99:1, contains a conductivity-imparting agent.
