PURPOSE: To provide braided rope structure which can easily retain the three- dimensional structure of the braided ropes with high stiffness, strength and large volume.

CONSTITUTION: This braided rope structure B is constituted from a cylinder E of side walls S surrounding the hollow part V or a combination of the hollow parts. As it has the hollow part V, the structure can be impregnated with a resin from its inside until the resin can deeply reach the inner part in a shortened time with the productivity increased. Such impregnation of the structure B with a resin enables the formed products to have increased stiffness and strength with improved precision. Further, the structure B can also be formed into other desired forms by resin impregnation.
