Next, the interiors of the respective flow paths 8 are evacuated and, after that, charged with the predetermined amounts of working fluids. Next, by heating the plate-like member 7 side with heating sources such as heaters or the like, the working fluids 9 in the respective flow paths 8 are heated and turned into steam so as to diffuse in the spaces in the flow paths in order to discharge heat from the steam at the low temperature top surface sides in the flow paths 8 as the latent heat of condensation and liquefy the steam. Then, this liquefied working fluid 9 falls by gravity to the under surface sides of the flow paths for refluxing. By successively repeating the above-mentioned action, the heat is carried from the heating sources to the top surface of the surface plate 10, resulting in heating workplaces 6 placed on the top surface of the surface plate 10.
