A storage case accommodates a plurality of medical elongated bodies, which are assembled when used, and includes a plurality of pipe bodies wound to form a ring-like shape that are connected to each other in order to accommodate each of the medical elongated bodies, and a package case that collectively accommodates the plurality of connected pipe bodies. At least two of the pipe bodies are disposed side by side so as to overlap each other in a state in which the center axes of winding are deviated, and the pipe bodies have opening portions arranged so that the medical elongated bodies can be assembled within the storage case using no more than two hands.
