To provide an apparatus for an oxidation-reduction reaction, which makes the oxidation-reduction reaction efficiently proceed without using high voltage applied from the outside.
This apparatus for the oxidation-reduction reaction has an electrode pair 1 consisting of a semiconductor layer 2 which is used as an anode and is formed of diamond doped with high-concentration boron and a semiconductor layer 3 which is used as a cathode, is formed of such diamond doped with high-concentration boron as to have a higher work function than the semiconductor layer 2 has, and is placed on the other face of the semiconductor layer 2 while being electrically connected to the semiconductor layer 2. Here, the semiconductor layer 3 is prepared so as to have a different work function from that of the semiconductor layer 2, by 0.03 to 9 eV. The electrode pair 1 is then immersed in a solution 4 containing cations and anions.
