PROBLEM TO BE SOLVED: To provide a thermal storage material microcapsule carrying out heat absorption of heat energy during melting and heat radiation of the heat energy during solidification in each different temperature region and having high heat quantity and excellent thermal storage performances without using a plurality of kinds of organic thermal storage materials in a thermal storage material microcapsule encapsulating the organic thermal storage material.;SOLUTION: The thermal storage material microcapsule encapsulating the organic thermal storage material in a microcapsule is obtained by forming the film of the thermal storage material microcapsule by an interfacial polymerization method or a radical polymerization method. The difference between the melting temperature and the solidifying temperature of the organic thermal storage material in a state encapsulated in the microcapsule is set at ≥5°C. The average particle diameter of the thermal storage material microcapsule is preferably set at ≥0.1 to ≤12 μm. The purity of the organic thermal storage material is more preferably set at ≥80%. The acid value thereof is more preferably set at ≤3. The hydroxyl value is more preferably set at ≤10.;COPYRIGHT: (C)2007,JPO&INPIT
