Abstract
The present invention relates to a polyamide resin composition comprising polyamide (X) comprising a diamine unit containing 70 mol % or more of a metaxylylenediamine unit and a dicarboxylic acid unit and an alkali compound (A), wherein the following equations (1) to (4) are satisfied:10≦([COOH]—[NH])≦80  (1)0.32≦<6.46  (2)0.50≦<17.00  (3)2≦≦3  (4)wherein [COOH] represents a concentration (μeq/g) of a terminal carboxyl group in the polyamide (X); [NH] represents a concentration (μeq/g) of a terminal amino group in the polyamide (X); P represents a mole concentration (μmol/g) of a phosphorus atom contained per g of the polyamide resin composition; and M represents a sum (μmol/g) of values obtained by multiplying a mole concentration of an alkali metal atom and a mole concentration of an alkaline earth metal atom each contained per g of the polyamide resin composition by valencies thereof respectively.
