PROBLEM TO BE SOLVED: To improve the cooling efficiency by remarkably activating flowing of a refrigerant circulated through a refrigerant passage of a refrigerant pipe in a thermo-siphon type heat transfer body provided with a heat receiving part and a heat radiating part positioned substantially in the horizontal direction and with a refrigerant pipe disposed horizontally. SOLUTION: This thermo-siphon type heat transfer body includes the heat radiating part 1 and the heat receiving part 2 disposed in horizontal positions, wherein the heat radiating 1 has a plurality of flat refrigerant pipes 10, and a heat receiving side header block 20A and a heat radiating side header block 20B joined to each one end and other end of the refrigerant pipe 10. The refrigerant pipes 10 of the heat radiating part 1 are set in the horizontal to vertical attitude in which the whole is horizontal and the width direction is laid along the vertical direction, and the refrigerant passages Z of the respective header blocks 20A, 20B with which a plurality of refrigerant passages X formed on the refrigerant pipes 10 are connected are extended in the vertical direction to thereby accelerate flowing of the refrigerant circulated through the refrigerant passages Z.
