A flexbeam having a flapping part and a feathering and lead-lag part has a first composite member having a plurality of first layers and a plurality of second layers; and a second composite member having a plurality of loop members; wherein the flapping part is constructed such that the first layers of the first composite member and the second composite members arranged on the leading edge side and the trailing edge side of the beam, are jointed integrally and also the second composite members are separated by the second layers of the first composite member in a vertical direction and are jointed to the second layers, and the feathering and lead-lag part is constructed by jointing integrally the second layers of the first composite member arranged in a center of thickness, and the second composite members arranged on upper and lower surfaces of the second layers.
