<P>PROBLEM TO BE SOLVED: To provide a polyamide resin composition excellent in rigidity after water absorption (water absorption rigidity), rigidity under high temperature use (rigidity at heating), appearance, and flame retardancy. <P>SOLUTION: The polyamide resin composition includes: (A) a polyamide copolymer; and (B) a phosphinate and/or a diphosphinate. The polyamide copolymer includes: a dicarboxylic acid component unit including (a-p) adipic acid unit, (b-p) isophthalic acid unit, and (c-p) 1,4-cyclohexanedicarboxylic acid unit; and a diamine component unit, wherein the relation of the content (mol%) of the (b-p) and the content (mol%) of the (c-p) based on 100% by mol of the dicarboxylic acid component unit including the (a-p), the (b-p), and the (c-p) satisfies the following formula (1): (the content of the (c-p))>(the content of the (b-p))≥0.1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
