In a cooling system for cooling first and second heat-generating members, the first heat-generating member is cooled by a refrigerator, and cold produced by the refrigerator is stored in a cold storage unit, so that both the first and second heat-generating members can be continuously cooled by only using a single adsorption unit. Therefore, production cost of the cooling system can be reduced. Further, because the second heat-generating member is cooled through the cold storage unit, a temperature change in the adsorption unit immediately after a switching between an adsorbing mode and a desorbing mode can be absorbed in the cold storage unit. Accordingly, the heat-generating members can be stably cooled while the component number of the cooling system can be decreased.
