PURPOSE: To collect and remove bubbles by moving liquid in a vessel and applying large electric force to the bubbles moved when removing bubbles in liquid in the gravity-free environment or the in the micro gravity environment.
CONSTITUTION: In the outer circumference of a vessel 1 holding liquid 2 including bubbles 3 is arranged an electrohydrodynamics pump element 12 for moving the liquid 2 in the vessel 1 upward. In the upper part of the vessel 1 is installed a mesh-shaped electrode 8 formed by connecting wires 4, 5 to an AC power source 9. When the bubbles 3 in the liquid 2 moved by the electrohydrodynamics pump element 2 are conveyed to the mesh-shaped electrode 8, they are collected in the mesh central part with weak electric field by the mesh-shaped electrode 8. The bubbles 3 come into contact with gas in outside space 15 at top of the vessel to remove them.
