Abstract: Used as a heat transport medium to be transported with a fluid that is liquid in an operating temperature range is a medium in which a latent heat storage material is penetrated in a porous material, wherein the latent heat storage material is incompatible with the fluid and has a melting point within the operating temperature range, and the porous material has a liquid repellency to the fluid, an affinity for the latent heat storage material, and a sponge hardness of not more than 50. This achieves stable heat transport with a high heat conversion efficiency even by circulating the medium through a pipeline over a long period of time. The porous material may have continuous pores. The porous material may have a void ratio of not less than 50%. The porous material has an apparent density of about 0.05 to 0.5 g/cm3. The ratio of the latent heat storage material is about 100 to 5000 parts by weight relative to 100 parts by weight of the porous material. The porous material may contain a water-repellent lipophilic resin. The porous material may have a polyorganosiloxane skeleton.
