PROBLEM TO BE SOLVED: To provide a loop type heat pipe capable of ensuring flatness of a surface on a heating component side of an evaporation part even in a case of performing thinning, and having high heat transfer efficiency between the evaporation part and the heating component.SOLUTION: A loop type heat pipe includes: an evaporation part 31 that heats working fluid with heat transmitted from a heating component 35, thereby to generate steam; a condensation part that condenses steam generated in the evaporation part 31; a liquid pipe that communicates between the evaporation part 31 and the condensation part and in which the working fluid in a liquid-phase state circulates; and an evaporation pipe that communicates between the evaporation part 31 and the condensation part and in which the working fluid in a gas-phase state circulates. Also, the evaporation part 31 has a base sheet 51 to which heat is transmitted from the heating component 35 to a one-side surface side, and a cover sheet 52 that has a lower rigidity than the base sheet 51 and is arranged oppositely to the other surface of the base sheet 51.SELECTED DRAWING: Figure 13 |
