This fiber-reinforced composite material has a textile base material containing a laminated plurality of oblique textile layers. Each of the oblique textile layers is configured from weaving a plurality of first reinforcing fiber bundles and a plurality of second reinforcing fiber bundles that are oblique with respect to the first reinforcing fiber bundles. The plurality of oblique textile layers are laminated in a manner such that for adjacent pairs of oblique textile layers in the direction of lamination, the orientation direction of either the first or second reinforcing fiber bundles in one oblique textile layer is the same as the orientation direction of either the first or second reinforcing fiber bundles in the other oblique textile layer. A single-orientation layer configured from a plurality of fiber bundles is disposed between oblique textile layers that are adjacent in the direction of lamination. The single-orientation layer is disposed in a manner such that the orientation direction of the fiber bundles of the single-orientation layer is the same as the orientation direction of the reinforcing fiber bundles having the same orientation direction as each other in the adjacent oblique textile layers.
