PROBLEM TO BE SOLVED: To provide a substrate storage case capable of reducing a production cost of a substrate for a magnet disk by reducing a recovery cost and cleaning cost.SOLUTION: A case body 2 for storing an RTP substrate W and a holding part 6 for holding the RTP substrate W in a positioned state in the case body 2 are formed by a disposable packaging material. The holding part 6 is formed in a bellows shape by folds formed at a sheet material and holds the outer circumferential edge of the RTP substrate W at least at a pair of the opposite surfaces of the case body 2. |
