Zusammenfassung:	To provide a latent heat storage material with which an article to be kept cold such as frozen food and ice cream can be kept cold at a temperature of -20°C or less for a long time, the material being capable of reducing the electric power consumption necessary for solidification.SOLUTION: The latent heat storage material contains 5-21 pts.wt. of ammonium chloride, 2-13 pts.wt. of potassium chloride, 5-23 pts.wt. of urea, and 43-88 pts.wt. of water, with the total of ammonium chloride, potassium chloride, urea and water being 100 pts.wt. The latent heat storage material has a main melting point in the range between -20°C and -23°C.SELECTED DRAWING: Figure 4 【課題】冷凍食品やアイスクリームのような被保冷物を－２０℃以下の温度で長時間保冷することができ、かつ凝固時に必要な消費電力を低減できる潜熱蓄熱材を提供する。【解決手段】潜熱蓄熱材は、５～２１重量部の塩化アンモニウムと、２～１３重量部の塩化カリウムと、５～２３重量部の尿素と、４３～８８重量部の水と、を含み、塩化アンモニウム、塩化カリウム、尿素及び水の合計が１００重量部であり、－２０℃～－２３℃の範囲に主たる融点を有する。【選択図】図４
