PROBLEM TO BE SOLVED: To conduct a reduction in weight, a simplification of a structure and an improvement in flexibility of a shape by predicting a use particularly in space and to endure against a practical use. SOLUTION: A polyhydric alcohol aqueous solution having 4 carbons or more of a non-azeotropic composition is used as a working liquid of a heat pipe, thereby operating a temperature difference Marangoni's effect and a concentration difference Marangoni' effect in the same direction, and improving a circulating efficiency of the liquid from a condenser to an evaporator. Further, a wall surface of a closed container contacted with the liquid is interfacially treated to be hydrophilic, thereby releasing no liquid from the wall surface even in a zero gravity environment, and hence maintaining a function as the pipe.
