A thermoduct comprises a metallic tube with multiple trenches, cupric powder and a metallic net, wherein the metallic net and the cupric powder are disposed inside the metallic tube and function as a capillary texture. The cupric powder is sintered to adhere to recesses of trenches, and the metallic net is sintered to adhere to the inner wall of the metallic tube. In the present invention, the metallic net can confine the cupric powder inside the gap between the metallic net and the inner wall of the metallic tube, which enables the cupric powder to be sintered to firmly adhere to the recesses of the trenches; thus, the thermoduct can simultaneously have capillarity, permeability and thermal conductivity, and the backflow of the liquid working fluid is speeded up.
