PROBLEM TO BE SOLVED: To improve a heat transporting efficiency from a high temperature position to a low temperature position isolated from each other by reducing a heat discharge amount at an intermediate portion in a heat pipe having one end of a container as a heating part and the other end as a heat radiating part. SOLUTION: The heat pipe 1 having a container 2 made of a sealed pipe for sealing a condensable fluid as a working fluid in a degassed state therein, one end as a heating part 3 and the other end as a heat radiating part 4, comprises a thin film layer 6 of a surface having a lower emissivity than that of the part 4 and provided at an intermediate part 4 between the part 3 and the part 4. |
