PURPOSE: A cryo-vessel for a superconducting power device is provided to improve measurement accuracy by significantly reducing a level detection error of a cryogenic liquid due to a measurement error and external noise. CONSTITUTION: A storage member(10) comprises a storage part(10a) for storing cryo-vessel. The storage member comprises an external casing part(11) and an internal casing part(12). An external side surface and the bottom surface of the internal casing part are arranged by being separated from an external side surface and the bottom surface of the external casing part. A conductor member(20) for measuring a level is arranged within the storage part. A container cover member(30) covers the upper part of the storage member.
