PROBLEM TO BE SOLVED: To provide a polyamide resin composition that has excellent heat resistance, strength and rigidity, and specifically show high surface impact strength at low temperature. SOLUTION: The polyamide resin composition is composed of polyamide resin and a swellable fluorine mica that is produced by using talc as a starting material, has the following structure represented by Na<SB>α</SB>(Mg<SB>x</SB>Li<SB>β</SB>)Si<SB>4</SB>O<SB>y</SB>F<SB>z</SB>(wherein 0<α≤0.50, 0<β≤0.50, 2.5≤x≤3, 10≤y≤11, 1.0≤z≤2.0 andα/β=90/10 to 10/90) and the blend ratio of sodium silicofluoride and lithium silicofluoride is 45/55 to 35/65 in molar and the exchange of the cation is 50 to 70 mm equivalent/100 g.
