Abstract
A fiber-reinforced polyamide resin base material comprises continuous reinforcing fibers, or comprises a reinforcing fiber base material in which discontinuous reinforcing fibers are dispersed, impregnated with a polyamide resin. In the polyamide resin, at least part of the polymer constituting the polyamide resin is an end-modified polyamide resin having, at an end group of the polymer, a structure constituted by a structural unit different from a repeating structural unit constituting the backbone of the polymer. A fiber-reinforced polyamide resin base material having an excellent impregnation property and thermal stability, less void, and excellent surface quality is provided.
