Abstract
A latent-heat storage material composition includes: a latent-heat storage material for storing or releasing heat by utilizing absorption or release of latent heat in association with phase change; and additives mixed with the latent-heat storage material. The additives can adjust a property of the latent-heat storage material. The additives include a first additive, which is a water-soluble substance belonging to polysaccharides and is gellan gum, which is also a thickener for increasing the viscosity of a melt of the latent-heat storage material composition in a liquid phase state, based on interaction of the thickener with water contained in the latent-heat storage material composition and cations. The content of the gellan gum is 1 wt % or less of the weight of the whole latent-heat storage material composition.
