PROBLEM TO BE SOLVED: To provide a plasticizer-containing polyamide resin composition which exhibits no bleed-out of a plasticizer, can attain sufficient high molecular weight as compared with conventional polyamide 92, and has a wide moldable temperature range estimated from the difference of melting point and thermal decomposition temperature and is excellent in melt moldability, and further has better chemical resistance, flexibility, hydrolysis resistance etc. than a conventional aliphatic polyamide resin without impairing low water absorption properties seen in a linear aliphatic polyoxamide resin. SOLUTION: The plasticizer-containing resin composition includes a polyamide resin and a plasticizer. In the polyamide resin, the dicarboxylic acid component is composed of oxalic acid; the diamine component is composed of C9 diamine (a mixture of 1, 9-nonanediamine and 2-methyl-1, 8-octanediamine) and 1, 6-hexanediamine; and the molar ratio of the C9 diamine to 1, 6-hexanediamine is 1:99 to 99:1.
