A reinforced polyamide resin composition which involves 100 parts by weight of a polyamide and from 0.01 to 100 parts by weight of fluoromica-based mineral with swelling characteristics. A process for producing the reinforced polyamide resin composition involving polymerizing a monomer in a state where from 0.01 to 100 parts by weight of fluoromica-based mineral with swelling characteristics is present per the monomer in an amount of forming 100 parts by weight of a polyamide. The reinforced polyamide resin composition is excellent in mechanical strength, toughness, heat resistance and dimensional stability.
