Abstract: A heat pipe includes a flat container having an internal space in which a working fluid is sealed and a flat surface facing the internal space, and a wick disposed in the internal space. The wick includes a first wick having a plurality of first voids and a second wick having a plurality of second voids. The first wick rises from the flat surface and is fixed to the flat surface. The second wick is formed of a sintered body of powders and covers a surface of the first wick. Each of the plurality of second voids is smaller on average than each of the plurality of first voids.
