PROBLEM TO BE SOLVED: To achieve reduction in cost and miniaturization in a device for transferring liquid helium by temporally pressurizing inside a liquid helium container, generating air column vibration, applying the vibration to the liquid helium inside, vaporizing the liquid helium, and raising the pressure in a tank when transferring the liquid helium container to a position desired. SOLUTION: This liquid helium pressurizing and transferring device is provided with the container 4 for storing the liquid helium, a pipe passage 3 such as a rubber pipe for transferring the liquid helium 2 in the container 4 to the desired position 1, a solenoid valve 6 and the pressurizing tank 7 in a pressurizing pipe passage 11 communicating to a vapor phase part 8 in the container 4 from the container 4 side in order, a small pump 5 for supplying the helium gas between the container 4 and the solenoid valve 6 in the pressurizing pipe passage 11 to the pressurizing tank 7, and a control device 13 for intermittently opening and closing the solenoid valve 6. The small pump 5 is continuously operated and the pressurizing tank 7 is kept in a predetermined pressure. The control device 13 equipped with a timer is released for a short period. Thus, the air column vibration is generated in the container 4.
