Abstract: A reinforced fiber/resin fiber composite is provided in which the ratio and arrangement of a long fiber and a thermoplastic resin fiber included in an intermediate material are accurately controlled to simultaneously provide good impregnation characteristics of the long fiber and good interfacial characteristics between the long fiber and the thermoplastic resin. A reinforced fiber/resin fiber composite (50) is provided which is an intermediate material for a long-fiber reinforced thermoplastic resin structure. The reinforced fiber (15) is a long fiber extending in a longitudinal direction. The resin fiber (25) includes at least two thermoplastic resin fibers. The at least two thermoplastic resin fibers are arranged around the reinforced fiber (15) to surround the reinforced fiber (15).
