PROBLEM TO BE SOLVED: To provide a hollow layered structural body in which an internal shape of each plate-like body, and positional deviation of the plate-like bodies in a vertical direction, a horizontal direction and a rotating direction can be easily confirmed even in a state where the plate-like bodies are layered. SOLUTION: The hollow layered structural body 1000 is configured by layering the plurality of plate-like bodies each of which has circular first and second hollow parts 1000a1, 1000a2 for indicating shapes of circular hollow parts 1000a, 1000a. Further, when the plate-like bodies are layered, the first hollow part 1000a1 and the second hollow part 1000a2 formed on the each of plate-like bodies are formed into similar figure and configured concentrically so as to become smaller at a fixed ratio in accordance with the layering order from the top.
