<P>PROBLEM TO BE SOLVED: To provide a polyamide resin composition and a molded article that have excellent stability of surface appearance and impact resistance characteristics and less defective molding due to molding condition change. <P>SOLUTION: The polyamide resin composition includes (A) 100 pts.mass of a polyamide which comprises (a) a unit composed of adipic acid and hexamethylenediamine and (b) a unit composed of isophthalic acid and hexamethylenediamine and in which the isophthalic acid component ratio (x) in the total carboxylic acid component is 0.05≤(x)≤0.5, (Y) represented by formula (1):-0.3≤(Y)≤0.8 and (Y)=[(EG)-(x)]/[1-(x)], (wherein (EG) is the ratio of isophthalic acid terminal groups in the total carboxy terminal groups contained in (A) the polyamide and shown by formula (2): (EG)= isophthalic acid terminal group amount/total carboxy terminal group amount) and (B) 1-200 pts.mass of a specific inorganic filler. <P>COPYRIGHT: (C)2013,JPO&INPIT |
