PROBLEM TO BE SOLVED: To provide a frame structure suitable for a large canopy structure while being excellent in rigidity and foldable into a compact state. SOLUTION: The invention is a dome-like polyhedral structure formed of a plurality of rhombic lattices wherein a first stage of continuous rhombi lattices, composed of n (n≥3) pieces of rhombic lattices, is arranged in such a way as to be connected by sharing mutual apex and upper lattice frame and going around the apex. Furthermore, a second stage of rhombic lattice is arranged so as to be connected under the first stage continuous lattices by sharing lower lattice frames of the lattices. The lattice frame of the structure is formed as a support member and a contact point of the lattice frame is formed as a connection part while each connection part is formed as an activating connector, so that the structure has a rigidity and also can promptly be contracted/spread.
