<P>PROBLEM TO BE SOLVED: To provide a microencapsulated heat-accumulating solid material consisting of a solid microcapsule containing a latent heat accumulating material, enabling the production of the solid material without causing the breakage of the microcapsule and usable over a long period without lowering the heat-accumulation effect even by repeating the temperature change in a temperature range including the phase-transition temperature. <P>SOLUTION: The microencapsulated heat-accumulating solid material producible without causing the breakage of the microcapsule and keeping the heat-accumulation effect even by repeating the temperature change passing through the phase-transition temperature can be produced by using a solid microcapsule containing a latent heat accumulating material, and having a volume-average particle diameter of <3.5μm and a capsule wall thickness of ≥1 nm and ≤100 nm. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
