PURPOSE:To provide a body which does not become liquid and can be handled as a solid even when the compnent latent heat storage material is molten, can remain soft and elastic even when the latent heat storage material is solidified. CONSTITUTION:The body is prepared by dispersing an oily substance and an organic heat storage material in a base comprising an ethylene/alpha-olefin copolymer A having a density lower than 0.926g/cm<3>. In order that this body can retain its shape and does not lose its strength at high temperature, it is prepared by dispersing an oily substance and an organic heat storage material in a base comprising copolymer A and at least one member selected from among an ethylene/alpha-olefin copolymer B having a density higher than that of copolymer A, a medium-density polyethylene and a high-density polyethylene. |
