Heat pipes comprising an outer tubular material closed at both ends, a wick of metal fibers, an inner tubular material covered with the wick and inserted in the outer tubular material and a heat transfer volatile liquid confined in the closed outer tubular material. An evaporation region and a condensing region are respectively constituted in the end portions of the outer tubular material. The liquid in the evaporation region vaporizes when heated and the vapor is passed to the condensing region to condense while giving the heat of the vapor to other materials outside the heat pipe, and the condensed liquid is returned to the evaporation region by the capillary action of said wick, thus repeating a cycle of the evaporation and condensation.
