Abstract: A rod-shaped FRP bar is manufactured with a fiber and a resin by using a nozzle 100 which includes an outer nozzle 11 having a penetration hole at its center and a plurality of middle nozzles 12 disposed at an inlet of the outer nozzle 11 so that one middle nozzle is located inside another middle nozzle with an interval. Fibers are supplied through a center hole of the middle nozzle located at an innermost location, through intervals between the middle nozzles and through intervals between the middle nozzles and the outer nozzle, thereby making a hybrid FRP bar 1 having a section in which the fibers configure a plurality of fiber distribution layers from the center of the FRP bar toward the outside.
