PROBLEM TO BE SOLVED: To provide a cooling device capable of efficiently performing a cooling operation. SOLUTION: This cooling device 32 comprises a secondary circuit 44 constituted by connecting a secondary heat exchanging section 46 condensing a gas-phase refrigerant to obtain a liquid-phase refrigerant, and an evaporator EP for evaporating the liquid-phase refrigerant to obtain a gas-phase refrigerant by liquid piping 48 and gas piping 50, for circulating the liquid-phase refrigerant from the secondary heat exchanging section 46 to the evaporator EP through the liquid piping 48, and circulating the gas-phase refrigerant from the evaporator EP to the secondary heat exchanging section 46 through the gas piping 50. The cooling device 32 further has a communication pipe 54 connected with the gas piping 50, and an expansion tank 56 connected with the communication pipe 54 at one end section and closed at the other end section, and the circulation of the refrigerant to an expansion tank 56 side is adjusted according to an internal pressure of the secondary circuit 44 by a solenoid valve 58 inserted fitted to the communication pipe 54.
