Zusammenfassung:A cold storage material and a cold storage pack are provided where a single cooling medium (cold insulation pack) containing a cold storage material having a plurality of melting points can keep an object at a low temperature that is suited to a situation. The cold storage material changes phase at a prescribed temperature and contains: water; a base compound containing a quaternary ammonium salt that forms a semi-clathrate hydrate; and a supercooling inhibitor that suppresses supercooling, wherein the cold storage material has one or more melting points depending on a temperature range in which the cold storage material has been frozen. These features allow the user to set the melting point of the cold storage material as he/she wants, by properly changing the freezing temperature for intended usage
