Abstract
The present disclosure provides a latent heat storage material that has a low risk of leakage and a low moisture absorbency that is highly workable. The latent heat storage material includes a heat storage material and a surface layer containing a cured product of a reaction curable liquid resin. The heat storage material contains an inorganic latent heat storage material composition containing an inorganic latent heat agent and a thickener. The surface layer has a specific type E hardness value, a specific 100% modulus, and a specific elongation percentage at break.
