PURPOSE:To provide a novel defoaming device for micro-gravity environment where only bubbles mixed in liquid are effectively removed in the micro-gravity environment and also the miniaturization of equipment is attained. CONSTITUTION:In a defoaming device for micro-gravity environment which is connected to a thermal control system loop used in micro-gravity environment, such as space and for removing bubbles mixed in liquid in the thermal control system loop, a gas mixed liquid introducing pipe 8 is tangentially connected to the end of a casing 7 in the form of a barrel so that the gas mixed liquid in the thermal control system loop may be introduced to give it swirling flow and a hydrophobic hollow fiber membrane tube 11 is installed in the axial central part in the casing 7 along its longitudinal direction so that the separated gas may be absorbed and also the tip part of the hollow fiber membrane tube 11 is closed and the rear end part is provided with a suction means.
