<P>PROBLEM TO BE SOLVED: To provide a module for the dissolution of gas whose bulk is small and which can increase gas solubility. Ž<P>SOLUTION: A dissolver body 110 forms an internal space 111 for dissolving gas, an inflow port 112 and an outflow port 113 are formed at the dissolver body 110 for the inflow and outflow of liquid, respectively, and a gas injection port 114 and a gas exhaust port 115 are formed at the dissolver body 110 for the injection and exhaust of gas, respectively. At this time, a circulation pipe 120 is formed in such a manner that the gas exhaust port 115 and the inflow port 112 are connected, so as to form a circulation passage through which undissolved gas is re-injected into the dissolver body 110, wherein the dissolution of gas and the collection of undissolved gas are realized in an equal space, so as to reduce the bulk of the module for the dissolution of gas, and, by re-injecting undissolved gas into the dissolver body 110, gas solubility can be increased.
