A bubble column reactor includes a reactor body which contains a slurry having solid catalyst particles suspended in a liquid, an inflow port which is provided at the bottom of the reactor body and allows a synthesis gas including a carbon monoxide gas and a hydrogen gas as the main components to flow into the slurry therethrough, and an outflow port which is provided at the top of the reactor body and allows gaseous hydrocarbons synthesized by a chemical reaction between the synthesis gas and the slurry, an unreacted synthesis gas, and the like to flow out therethrough. The distance in a vertical direction between the liquid surface of the slurry and the outflow port is 1.4 m or more and 10 m or less.
