    • PURPOSE: To obtain a heat pipe more efficient than transmitting heat from electronic parts to the outside by providing a cylindrical tight-closed container containing a flexible bellow having an evaporating portion at one end and a condensation portion at the other end, a first wick covering the inner side of the evaporating portion, a second wick covering the inner side of the condensation portion, and placing the wick in a length direction inside the cylindrical container for connecting the evaporation portion to the condensation portion. CONSTITUTION: A wick 26 penetrated with an operation fluid 36 is attached to the inner side 25 a bellows type container 18. The bottom portion of the bellows type container 18 is called an evaporation portion. A hollow cylindrical condensation portion 20 is attached in an airtight manner to the top end surface 24 of the bellows type container 18. Whole inner surfaces of the condensation unit 20 is equipped with a circumferential wick 30 and a radial wick 32. A wave-shaped slab wick 28 of a rectangular cross section shape is arranged in a length direction inside the heat pipe. This slab wick 28 is flexible and is connected to the wick 26 and 32 or the evaporation portion and the condensation portion.
