The present invention provides a method for producing formic acid, which is a useful substance from carbon dioxide having excellent environmental and energy efficiency. A porous metal complex capable of occluding carbon dioxide, an amphiphilic electron donor such as 1,1′-dimethyl-4,4′-pipyridinium, and the porous metal complex are combined. In addition, a step of electrolytically reducing carbon dioxide to produce formic acid in an aqueous medium containing a trinuclear transition metal sulfur cluster catalyst such as [(C5H5Co) 3S2].
