Description of the Related Art As a latent heat storage material utilizing latent heat accompanying a phase transition, a heat storage material in which an organic heat storage material such as paraffin is supported on a resin is known. The heat storage body is housed in an appropriate housing and can directly store heat and release heat by directly contacting the heat medium. However, for example, when it is used by incorporating it into a floor material, a wall material, etc., the installation location is limited,
Since the contact area between the heat storage medium and the heat medium is small, it is difficult to improve the heat exchange performance. Therefore, in order to increase the contact area between the heat storage medium and the heat medium, it has been studied to use the heat storage medium in the form of spherical or cylindrical particles.
