Abstract
Provided is a heat sink that can prevent dryout without impairing heat transfer characteristics even when an environmental temperature at the time of use is lower than a melting point of a working fluid. The heat sink includes a heat transport member including a heat receiving part thermally connected to a heat generating body, and a first heat radiating fin group in which a plurality of first heat radiating fins are arranged, the first heat radiating fin group being thermally connected to the heat transport member at a heat radiating part, the heat transport member has an inner space that communicates from the heat receiving part to the heat radiating part and in which a working fluid is sealed, and a heat transfer member is thermally connected to a heat insulating part located between the heat receiving part and the heat radiating part of the heat transport member.
