PROBLEM TO BE SOLVED: To provide a temperature control medium which is safe to eat, can be preserved stably at room temperature for a long term, and operates at a predetermined temperature. SOLUTION: The temperature control medium 10 is in a liquified state at the normal temperature and includes an emulsified liquid 11 which solidifies when cooled to a predetermined temperature and fuses and undergoes phase separation accompanied by a temperature rise. The emulsified liquid 11 is a lipid mixture containing water, fats and oils, and phospholipid. The average particle diameter of fine particles constituting the dispersed phase of the emulsified liquid 11 lies between 5μm and 30μm. COPYRIGHT: (C)2006,JPO&NCIPI
