Cooling device and electronic apparatus

An electronic apparatus, comprising:

• a heat generating component;
• and
• a cooling device for cooling the heat generating component, the cooling device including
• a circulation channel through which a refrigerant is circulated,
• a heat receiving part which is disposed in the circulation channel and in which the refrigerant receives heat generated by the heat generating component,
• a heat dissipating part which is disposed in the circulation channel and in which the refrigerant dissipates the heat received in the heat receiving part,
• a pump which is disposed in the circulation channel and which sends the refrigerant to the heat receiving part, and
• a tank which is coupled to the circulation channel and which has a space therein,
• a lower side of the tank is disposed at a higher position in a vertical direction than the pump in a state where the pump is located on an upper side in the vertical direction with respect to the heat receiving part and the heat dissipating part.
