A cooling device simple in structure, less in power consumption, and capable of reducing total costs, wherein outside air is circulated through the inside of a first flow passage (25) by a fan (12) so that water is evaporated forcibly on an evaporation sheet (34) to increase the amount of evaporation in order to absorb more heat than usual, whereby the temperature of a cooling unit (30) in contact with the evaporation sheet (34) is lowered suddenly, and thus the air in a room circulating through the inside of a second flow passage inside the cooling unit (30) can be cooled.
