Abstract: PURPOSE: To make it difficult to generate the dry out of a heat pipe and reduce a temperature over shoot caused by the generation of nuclear boiling of a vaporizing part by forming a groove on an inner surface of a metal pipe which constitutes a heat pipe in the axial direction of the metal pipe and further a groove in the peripheral direction of the metal pipe on an inner surface except for a heat input part. CONSTITUTION: In case when heat is added to a vaporizing unit 11 with a heating element, a working fluid 5, which is collected on the bottom of the vaporizing unit 11 starts vaporizing. The vaporized working fluid 5 moves to a condensation unit on which heat dissipation fins 2 are mounted and then condensed.

The working fluid 5, which has returned to the vaporization unit 11, is vaporized in a thin film state inside the groove 3 in the axial direction without nuclear boiling up.
