The electronic apparatus including the cooling system upon which it is difficult for the temperature of wind flowing in the passage to exert an influence, and yet which enables an efficient cooling accompanied by the generated heat temperature of the electronic part is provided. The electronic apparatus that includes a case, a fan arranged in the case, a plurality of electronic parts arranged in the case, and a heat sink that is mounted for each of desirable electronic parts, out of the electronic parts, and yet receives wind generated by the fan, thereby to cool the above electronic part, wherein the heat sink includes a fluid unit, and a shutter plate for controlling the quantity of wind flowing in the above heat sink generated by the fan with an action of the fluid unit that is actuated by heat of the electronic part, wherein said fluid unit is a unit obtained by filling up a container with liquid; wherein the container is arranged for the electronic part so that heat of the above electronic part is conducted with a heat conducting action; and wherein a configuration is made so that in a case where a generated heat quantity of the electronic part is large, the fluid inside the container arranged for the above electronic part expands, thereby allowing the shutter plate to operate in an opening direction, and increasing the quantity of wind flowing in the heat sink generated by the fan, and in a case where a generated heat quantity of the electronic part is small, the fluid inside the container arranged for the above electronic part shrinks, thereby allowing the shutter plate to operate in a closing direction, and reducing the quantity of wind flowing in the heat sink generated by the fan.
