Claim:
1. A process for producing a polyamide resin composition comprising: (a) polycondensating a diamine comprising 70 mol % or more of metaxylylenediamine and dicarboxylic acid in the presence of a phosphorus atom-comprising compound (B), to obtain a polyamide (X); and (b) adding an alkali compound (A) which is at least one selected to the polyamide (X) to form the polyamide resin composition, wherein the alkali compound (A) is at least one selected from the group consisting of sodium acetate, sodium acetate trihydrate, sodium carbonate decahydrate, lithium acetate dihydrate, and potassium acetate, wherein the polyamide resin composition, comprises: the polyamide (X) comprising a diamine unit comprising 70 mol % or more of a metaxylylenediamine unit and a dicarboxylic acid unit; and the alkali compound (A), wherein the polyamide resin composition produced satisfies equations (1) to (4): wherein [COOH] is a concentration (μeq/g) of a terminal carboxyl group in the polyamide (X); [NH P is a mole concentration (μmol/g) of a phosphorus atom contained per gram of the polyamide resin composition; and M is 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 gram of the polyamide resin composition by valencies thereof, respectively, for each alkali metal atom and each alkaline earth metal atom present in the polyamide resin composition.
