1. A heat transport device, comprising:
a sealed container from which air is evacuated; a working fluid that is encapsulated in the container, and that circulates within the container while being evaporated by being heated and condensed by removing heat therefrom; a fiber wick that is formed by bundling a plurality of fibers, and that is laid on an inner face of the container in a longitudinal direction; and a powder wick that is formed on a surface of the fiber wick by depositing particles whose grain diameters fall within a range between 5 to 10 μm that is five to ten times smaller than a diameter of the fiber; wherein a thickness of the powder wick is one to five times larger than the grain diameter of the particle.
