A nanobubble containing a useful substance as a constituent element and an apparatus for producing the nanobubble are provided. A useful substance-containing nanobubble generator of the present invention includes a mixing means, a supply means, and a nanobubble generating means. Therefore, in the mixing means 32, a mixed solution of the useful substance and the liquid is obtained, and in the supply means, a gas-liquid mixture of the mixed solution and the gas is obtained. Further, the nanobubble generating means 24 includes the gas / liquid mixing and circulation pump 11 having the gas / liquid suction pipe 15 and the liquid suction pipe 3, so that the gas / liquid mixture is discharged from the gas intake pipe 15. 11 can generate nanobubbles containing useful substances.
