This three-dimensional fiber-reinforced composite is provided with: a laminate having a plurality of fiber-bundle layers laminated in a laminating direction, the fiber-bundle layers including first and second outermost layers; a matrix resin; a retaining yarn; and a binding yarn for binding the fiber-bundle layers. The binding yarn has a folded-back section folded back through the outside of the retaining yarn, a first traverse yarn section and a second traverse yarn section continuous with the folded-back section, and a surface-layer yarn section that extends in a direction substantially orthogonal to the retaining yarn along the plane of the second outermost layer on the surface of the second outermost layer. The surface-layer yarn section has bifurcated sections extending in opposite directions from the first traverse yarn section and the second traverse yarn section on the surface of the second outermost layer. An additive and the matrix resin are arranged in a space enclosed by the bifurcated sections and the fiber bundle of the second outermost layer adjacent to the bifurcated sections, and also in a space between each of the first and second traverse yarn sections and fiber bundles adjacent thereto, and in a space between the first traverse yarn section and the second traverse yarn section.
