To provide a gas dissolving apparatus capable of more stabilizing gas-liquid mixing in a gas-liquid mixing tank of a dissolving tank even in such a state that the pressure in the gas-liquid mixing tank is enhanced.
The inside of a dissolving tank 2 of a gas dissolving apparatus 1 is partitioned into a gas-liquid mixing tank 6, intermediate tank 7 and gas-liquid separation tank 8 by the first and second partition walls 3 and 4. The first partition wall 3 partitioning the gas-liquid mixing tank 6 and the intermediate tank 7 has an irregularity M having protrusions M1 protruding toward a bottom wall 2b and recesses M2 denting toward an upper wall 2a. The clearances S which is a flow path of a gas-dissolved liquid 5 are formed between the irregularity M and the bottom wall 2b. In the clearance S, a clearance S2 of a portion corresponding to the recess M2 of the irregularity M is formed so that the bubbles coming to be mixed in the liquid 5 pass through the clearance.
