摘要：
The invention aims to provide a heat-storage material which can prevent supercooling.The heat-storage material according to the invention includes: a heat-storage substance which reversibly changes between an aqueous solution containing tetraalkylammonium salt and a clathrate hydrate containing the tetraalkylammonium salt as a guest molecule; and alum which is added to the aqueous solution containing tetraalkylammonium salt. Tetrabutylammonium bromide is used as the tetraalkylammonium salt. Potassium alum or ammonium alum is used as the alum.
