<P>PROBLEM TO BE SOLVED: To provide a polyamide resin composition and a molded article, which excel in stability of external appearance and impact resistance and hardly causes molding failure due to the change of molding conditions. <P>SOLUTION: The polyamide resin composition includes: (A) 100 pts.mass of a polyamide comprising (a) a unit composed of adipic acid and hexamethylenediamine and (b) a unit composed of isophthalic acid and hexamethylenediamine; and (B) 1-300 pts.mass of a fibrous reinforcing material having a D2/D1 ratio (flattening) of 1.5-10, wherein D2 is the major axis of the cross section of the fiber and D1 is the minor axis of the cross section of the fiber, wherein a ratio (x) of the isophthalic acid component to the entire carboxylic acid component is 0.05≤(x)≤0.5, (Y) represented by formula (1): (Y)=[(EG)-(x)]/[1-(x)] is -0.3≤(Y)≤0.8, and (EG) is represented by formula (2): (EG)=(amount of isophthalic acid terminal groups)/(amount of all carboxyl terminal groups). <P>COPYRIGHT: (C)2013,JPO&INPIT |
