A heat sink includes a first heat pipe having a flat plate-shape and a second heat pipe connected perpendicularly to the first heat pipe. The first heat pipe has a first wick provided along an inner surface thereof. The second heat pipe has a second wick provided along an inner surface thereof. Each of end portions of the first and second wicks in a connecting portion of the first and second heat pipes has a comb-toothed part formed in a convexoconcave form like teeth of a comb so that the first and second wicks are connected by the comb-toothed parts fitting to each other. The comb-toothed parts of the second wick traverses an interior of the first heat pipe and contacts with the first wick on an opposite side. |
