摘要： A degasifier includes a gas chamber, a degasification unit and a resistance applying unit. The gas chamber is separated from a liquid flow path by a transmission member capable of transmitting a gas dissolving in a liquid in the liquid flow path. The degasification unit expels the gas dissolving in the liquid from the liquid by discharging the gas in the gas chamber through a discharge path so that a pressure in the gas chamber is negative. The resistance applying unit applies an inflow resistance to atmosphere which flows into the discharge path so that the gas chamber is maintained at a pressure at which the liquid can be degasified at the time of the discharging by the degasification unit while the discharge path is open to the atmosphere at all times.
