Abstract
The cooling device comprises a base with a recessed part in a first surface, a plurality of heat radiating fins standing erect on a second surface on the reverse side of the first surface, and a flat, plate-like thermal diffusion part housed inside the recessed part. The upper surface of the thermal diffusion part makes thermal contact with the upper surface of the recessed part, the side surface of the thermal diffusion part makes thermal contact with the side surface of the recessed part, and the thermal diffusion part diffuses in the planar and orthogonal directions heat from the heat generating element arranged on the bottom surface of the thermal diffusion part by vaporizing and condensing coolant sealed inside.
