PROBLEM TO BE SOLVED: To provide a heat sink for attaining a surface, having a very high convection heat transfer characteristic per unit volume. SOLUTION: The heat sink comprises a diffused plate 30, having a recessed region on a certain surface and a flat region on the other surfaces, at least two fins 32, and a porous net-like foamed block 34, having interposed gaps 36 for partly filling a width and a length between the fins. The foamed block may be a single block which continues in a space between the two adjacent fins along a longitudinal direction of the fin or may be an array of short blocks, having the interposed gap along the longitudinal direction of the fin. |
