To provide a gas dissolving device capable of dissolving gas in liquid at high concentration.
A gas-liquid mixture ejector 15A is installed upward in a sealed tank 12. The sealed tank 12 has a gas chamber 14 at an upper part, where gas is accumulated, as opposed to a liquid chamber 13 at a lower part, where liquid is accumulated. The gas-liquid mixture ejector 15A jets upward gas-liquid mixture jet flow E formed by sucking liquid D in the sealed tank 12, into gas-liquid mixture flow of gas A and liquid B supplied to a lower part of the gas-liquid mixture ejector 15A by gas-liquid supply means 21A. The liquid in a gas dissolving state in the sealed tank 12 is taken out to the outside from a liquid take-out port 42 located under the gas-liquid mixture ejector 15A. The gas-liquid supply means 21A has a pump 37A for pressurizing the liquid B to be supplied to the gas-liquid mixture ejector 15A to such a degree that the gas-liquid mixture jet flow E jetted from the gas-liquid mixture ejector 15A can be spouted from a liquid level F in the sealed tank 12 to the gas chamber 14, and can splash in gas in the gas chamber 14.
