A wound body comprising a core member and a commingled yarn traversely wound onto the core member; the commingled yarn being constituted from continuous reinforcing fibers and continuous thermoplastic resin fibers; wherein the wound body is characterized in that the commingled yarn is traversely wound such that a gap is present between the commingled yarn and a closest commingled yarn traversely wound in the same direction; a dispersion degree of the continuous reinforcing fibers in the continuous thermoplastic resin fibers is 90% or more; an impregnation rate of the continuous thermoplastic resin fibers in the continuous reinforcing fibers is 5% or less; the commingled yarn is traversely wound in two to four directions; the commingled yarn is traversely wound in at least a direction from 3 to 25° and a direction from -3 to -25°, with respect to a straight line orthogonal to a center axis (c) of the core member; a ratio of a moved distance/width of commingled yarn, which is a ratio of a distance at which the commingled yarn is moved with regard to a central portion in the center axis (c) direction of the core member when the commingled yarn has been traversely wound one turn around the core member, to a width of the commingled yarn, is from 2.0 to 12.0; the commingled yarn is in a tape shape with a width from 7 to 20 mm; a ratio of a width of traverse winding/width of commingled yarn, which is a ratio of a width at which the commingled yarn is wound onto the core member to a width of the commingled yarn, is from 15 to 40; and a diameter of the core member is from 5 to 20 cm; where the dispersion degree is defined as a value that is obtained by embedding the commingled yarn in an epoxy resin, grinding a cross section perpendicular to a longitudinal direction of the embedded commingled yarn, photographing a cross-sectional view using an ultra-deep color 3D shape measuring microscope, drawing six equidistantly spaced auxiliary lines in a radial shape in the captured image, measuring lengths of continuous reinforcing fiber regions on each of the auxiliary lines as a1, a2, a3,...ai (i = n), measuring lengths of continuous thermoplastic resin fiber regions on each of auxiliary lines as b1, b2, b3,...bi (i = m), and then calculating the dispersion degree from the following equation: 1 − 1 n or m × ∑ i = 1 n or m a i or b i ∑ i = 1 n or m a i + ∑ i = 1 n or m b i × 100 %; and the impregnation rate is defined as a ratio at which the continuous thermoplastic resin fibers are impregnated into the continuous reinforcing fibers, and is a value expressed based on a ratio of a surface area of a cross section perpendicular to the longitudinal direction of the impregnated continuous thermoplastic resin fibers with respect to a surface area of a cross section perpendicular to the longitudinal direction of the commingled yarn. wherein the wound body is characterized in that the commingled yarn is traversely wound such that a gap is present between the commingled yarn and a closest commingled yarn traversely wound in the same direction;
