An electrolytic cell for carbon dioxide of an embodiment includes: an anode part including an anode to oxidize water or a hydroxide ion and thus produce oxygen and an anode solution flow path to supply an anode solution to the anode; a cathode part including a cathode to reduce carbon dioxide and thus produce a carbon compound, a cathode solution flow path to supply a cathode solution to the cathode, and a liquid passing member disposed between the cathode and the cathode solution flow path and having a pore allowing the cathode solution to pass through while holding the cathode solution; and a separator to separate the anode part and the cathode part from each other.
