PROBLEM TO BE SOLVED: To provide a polyamide resin composition having excellent heat resistance, strength and rigidity, and particularly high surface impact strength at a low temperature. A swellable fluoromica having a cation exchange capacity of 80 meq / 100 g or less represented by the following structural formula and having a surface impact strength at -30 ° C of 10 J or more. Characteristic polyamide resin composition. Na α (Mg x Li β ) Si 4 O y F z where 0 <α ≦ 0.50, 0 <β ≦ 0.50, 2.5 ≦ x ≦ 3, 10 ≦ y ≦ 11, 1.0 ≦ z ≦ 2.0, α / β = 90/10 to 10/90 It is. |
