Abstract
Provided is a material having large anti-piercing force and small surface roughness. The material contains continuous reinforcing fibers that are juxtaposed unidirectionally, and having a polyamide resin impregnated therein, wherein the continuous reinforcing fiber gives a non-circular cross sectional shape, when viewed perpendicularly to the longitudinal direction thereof, with a flatness ratio, given by long diameter (D2)/short diameter (D1), of 1.5 or larger, and in at least one cross section of the material taken perpendicularly to the direction of the continuous reinforcing fibers being juxtaposed, the percentage of area occupied by the continuous reinforcing fibers, whose long diameter (D2) lying at an angle of less than 20 degrees away from the direction of the continuous reinforcing fibers being juxtaposed, is 30 to 90% by area of the continuous reinforcing fibers.
