[Problem] To provide a heat sink that is lightweight and easy to process, while exhibiting excellent cooling performance. [Solution] This heat sink X1 is provided with a pseudo cylindrical shell 1 that is attached to an object to be cooled O1 and is formed using a heat dissipation sheet having a heat transfer layer 1A and a heat radiation layer 1B laminated on the heat transfer layer 1A. The heat radiation layer 1B is formed on at least the portion set apart from the object to be cooled O1 of the outer surface of the shell 1. |
