| Zusammenfassung: | The purpose of the present invention is to sufficiently reduce the melting point and sufficiently narrow the width of the melting peak while sufficiently ensuring the heat storage density in a heat storage material containing sodium acetate trihydrate as the main component. The heat storage material contains: a sodium acetate trihydrate as a main component (21); and a melting point adjusting material that is one of potassium nitrate, potassium chloride, and sodium nitrate. The content of the melting point adjusting material in the heat storage material is 10% by weight or more. The inventors have confirmed that when potassium nitrate, potassium chloride, or sodium nitrate is added to sodium acetate trihydrate, the melting point can be sufficiently reduced while sufficiently ensuring heat storage density. Furthermore, if the content of the melting point adjusting material is 10 wt% or more, the width of the melting peak, which is the melting temperature region, becomes sufficiently narrow.
