A concrete filled fiber reinforced plastic composite column is provided to prevent shear failure, and to restrain the formation of cracks in concrete caused by contraction or expansion by temperature by having large ductility of fiber reinforced plastics in case of a large cross section. A concrete filled fiber reinforced plastic composite column includes an inner cylinder tube(110) formed by joining a plurality of FRP unit members to arrange reinforcing fibers in the axial direction of a member, an FRP outer cover(120) covering the outside of the inner cylinder tube to arrange reinforcing fibers in the circumferential direction of the inner cylinder tube, and concrete(130) filled in the inner cylinder tube.
