<P>PROBLEM TO BE SOLVED: To provide a polyamide composition which excels in water absorption rigidity and rigidity when being heated, and is excellent in moldability at low temperature, and to provide a molding including the same. <P>SOLUTION: The polyamide composition includes: a polyamide copolymer having a dicarboxylic acid unit and a diamine unit; and at least one moldability-improving agent selected from the group consisting of a higher fatty acid, a metal salt of higher fatty acid, a higher fatty acid ester, and a higher fatty acid amide, wherein the dicarboxylic acid unit includes: an adipic acid unit; an isophthalic acid unit; and a 1,4-cyclohexanedicarboxylic acid unit, and in the polyamide copolymer, the content of the isophthalic acid unit is less than the content of the 1,4-cyclohexanedicarboxylic acid unit by the molar ratio. <P>COPYRIGHT: (C)2012,JPO&INPIT |
