Disclosed is a polyamide resin composition which comprises: a polyamide (X) composed of dicarboxylic acid units and diamine units that contain at least 70mol% of m-xylylenediamine units; and an alkaline compound (A). Further, the polyamide resin composition satisfies relationships (1) to (3): 0.03 = P < 0.32 ····· (1) 2.2 = M = 26.1 ····· (2) 5 < M/P = 200 ····· (3) In relationship (1) to (3), P is the molar concentration (µmol/g) of phosphorus in the polyamide resin composition; and M is the sum (µmol/g) of [(molar concentration (µmol/g) of alkali metal in the polyamide resin composition) × (the valency of the alkali metal)] and [(the molar concentration (µmol/g) of alkaline earth metal in the polyamide resin composition) × (the valency of the alkaline earth metal)].
