Abstract: A carbon dioxide reduction apparatus comprises a first electrochemical compartment provided with a first electrode, a second electrochemical compartment provided with a second electrode, an ion conducting membrane which demarcates the first electrochemical compartment from the second electrochemical compartment, and a first connecting path which connects the first electrochemical compartment with the second electrochemical compartment. The first electrode contains a first catalyst which catalyzes a reduction of carbon dioxide to a reduced product, and the second electrode contains a second catalyst which catalyzes a reaction between the reduced product and a reactant. The first connecting path is a connecting path which allows the reduced product in the first electrochemical compartment to flow out to the second electrochemical compartment.
