PURPOSE:To enhance deaeration velocity and to miniaturize the title apparatus by providing a vibrator for vibrating liquid in the case of deaerating liquid by evacuating it. CONSTITUTION:Air is drawn from a deaeration bottle 5 by closing an on-off valve 12 on an outlet side and opening an on-off valve 4 on an inlet side and actuating an exhaust pump 9, and the inside of the bottle 5 is evacuated and raw liquid 1 is introduced therein and when the raw liquid 1 is sufficiently introduced by means of a liquid level sensor 11, the valve 4 is closed and the inside of the bottle 5 is made to a state of negative pressure and gas incorporated in the raw liquid 1 is deaerated. In this case, the raw liquid 1 is agitated by rotation of a rotator 10 such as a magnetic stirrer or by ultrasonic wave or the like and vibration is given and deaeration velocity is enhanced. In such a way, the apparatus can be miniaturized since deaeration is efficiently performed.
