A cooling device comprising a thermal diffusing unit operable to radiate heat taken from a heating element, and a heat transporting part, laminated in a thickness direction of the heat diffusing unit and diffused thereby. The thermal diffusing unit has an upper plate, a lower plate opposite thereto, a vapor diffusion path to diffuse an evaporated refrigerant, and a capillary channel to circulate a condensed refrigerant. The heat transporting part has an upper plate, a lower plate opposite thereto, a vapor diffusion path to diffuse an evaporated refrigerant, and a capillary channel to circulate a condensed refrigerant. Either the upper plate or the lower plate is formed with the same member of the lower plate or the upper plate of the heat transporting part. |
