PROBLEM TO BE SOLVED: To explicitly indicate which positions of respective stories are connected with stairs in a structure which has a plurality of floors like a subway station. SOLUTION: In this atlas having holes, the plane figures of the respective floors of a structure are drawn on the front sides of respective paper sheets with an identical reduced scale, and these plane figures are arranged in a hierarchical order so that the stairs of the identical positions of the respective floors overlap and stairs which lead to down stairs are constituted of holes in the respective paper sheets. Since the stairs of the respective floors are communicated with holes, a passenger only needs to walk by following holes of stairs, so that the passenger can reach easily a target location from an entry on the ground, for example, to the platform of each subway.
