PROBLEM TO BE SOLVED: To provide a heat transfer device which can reduce a pressure loss of a refrigerant, enables the smooth execution of natural circulation of a refrigerant and prevention of scattering of condensate generated by an evaporator. SOLUTION: In the heat transfer device provided with a condenser 5 and the evaporator 9, interconnecting the condenser 5 and the evaporator 9 through a refrigerant liquid pipe 17 and a refrigerant gas pipe 19 and forming a natural circulation cycle, the evaporator 9 is provided with a header 23 on the liquid side in which refrigerant liquid flows; a header 25 on the gas side from which refrigerant gas flows out; and a plurality of straight pipes 27 intercoupling the two headers 23 and 25 and provided at the peripheries thereof with a plurality of fins 29. A water repellent filter 33 having air permeability is situated leeward of the evaporator 9.
