Provided are a continuous fiber-reinforced resin molding having high adhesion and compatibility in an interface between continuous reinforcing fibers and a synthetic resin, and in which a low occurrence of voids in the interface and adequate strength can be realized, and a method for manufacturing the same. A continuous fiber-reinforced resin molding comprising a synthetic resin and continuous reinforcing fibers having a substantially circular cross section, the continuous fiber-reinforced molding being characterized in that the number of continuous reinforcing fibers where the porosity in a peripheral-edge region separated by one tenth the radius of a single continuous reinforcing fiber from the peripheral edge part of the continuous reinforcing fibers in the interface between the synthetic resin and the single continuous reinforcing fiber in a cross section orthogonal to the length direction of the continuous reinforcing fibers is at least 10% of the total number of continuous reinforcing fibers.
A continuous fiber-reinforced molded resin comprising continuous reinforcing fibers with approximately circular cross-sections and a synthetic resin, wherein at the interface between each single continuous reinforcing fiber and the synthetic resin in a cross-section perpendicular to the lengthwise direction of the continuous reinforcing fiber, the number of continuous reinforcing fibers in which the void percentage within the region of the outer peripheral edge separated from the perimeter of the continuous reinforcing fiber by 1/10 of the radius of a single continuous reinforcing fiber is 10% or lower, is at least 10% of the total number of continuous reinforcing fibers.
