Disclosed are three-dimensional porous light-weight structures composed of helical wires and the manufacturing method of the same. Continuous helical wire groups in three or six directions having a designated angle (for example, 60 degrees or 90 degrees) with respect to one another in a space cross and are then assembled, and thus new truss-shaped three-dimensional lattice truss structures having high strength and stiffness to weight ratio and a large surface area and method of mass-producing the structures at low costs are provided. The three-dimensional porous light-weight structures are manufactured by a method in which helical wires are three-dimensionally assembled through a continuous process rather than a method in which net-shaped wires are simply woven and stacked, and thus have a configuration similar to the ideal hexahedron truss, Octet truss, or truss in which regular octahedrons and cuboctahedrons are combined, thereby having excellent mechanical properties or thermal or aerodynamic properties.
