To provide a heat pipe which reduces pressure loss caused when a gas phase working fluid and a liquid phase working fluid circulate to smoothen circulation of the liquid phase working fluid and thereby attain excellent heat transport characteristics.SOLUTION: A heat pipe includes: a container; a working fluid enclosed in an internal space of the container; a wick structure housed in the internal space of the container; and a gas-liquid separation member being a member which is provided in at least a part of a space between an inner surface of the container and an outer surface of the wick structure and has airtightness higher than airtightness of the wick structure. The gas-liquid separation member is disposed extending from an end part of an evaporation part of the container to the condensation part side.SELECTED DRAWING: Figure 1 【課題】本発明は、気相の作動流体と液相の作動流体が流通する際の圧力損失を低減し、液相の作動流体の流通を円滑化することで、優れた熱輸送特性を得ることができるヒートパイプを提供する。【解決手段】コンテナと、前記コンテナの内部空間に封入された作動流体と、前記コンテナの内部空間に収容されたウィック構造体と、前記コンテナの内面と前記ウィック構造体の外面との間の少なくとも一部に設けられた、前記ウィック構造体の気密性よりも高い気密性を有する部材である気液分離部材と、を備え、前記気液分離部材が、前記コンテナの蒸発部の端部から凝縮部側に伸延して配置されたヒートパイプ。【選択図】図１
