PURPOSE: To obtain the subject composition retaining the excellent characteristics of polyamides as one of its component, also excellent in flame retardancy, heat resistance and water resistance, useful for fibers, etc., by melt mixing a powdered phenolic resin cured product with a polyamide in specific proportions. CONSTITUTION: This resin composition is obtained by melt mixing (A) 100 pts.wt. of a polyamide with (B) 5-50 pts.wt. of a powdered phenolic resin cured product (pref. with an acetone extraction rate of <=10% and a particle diameter of 1-100μm). It is preferable that the component B be obtained by blending a novolak-type phenolic resin with a curing agent followed by curing under heating, or by curing a resol-type phenolic resin under heating or using an acid.
