Abstract: Provided are a reactor that can operate stably without being subject to restrictions on heating temperature, a gas production apparatus (that is, an industrially advantageous gas production apparatus) having the reactor, a gas production system, and a gas production method. Each of reactors 4a and 4b includes a container 41 having a single internal space 410 through which gas is capable of passing and a reducing agent layer 42 with which the internal space 410 is filled and which is configured by a reducing agent 4R reducing carbon dioxide to carbon monoxide. When the container 41 is cut in a direction orthogonal to a passage direction of the gas, a proportion of a cross-sectional area of the reducing agent layer 42 to a cross-sectional area of the internal space 410 is equal to or greater than 60%.
