Provided is an enzyme electrode in which oxidation-reduction reactions proceed with an enzyme acting as a catalyst, and the enzyme is modified to increase affinity and/or reaction rate with a reaction substrate or an electron transfer mediator by adding or inserting at least one codon encoding a particular amino acid residue to or into a base sequence encoding the enzyme, and is immobilized. Since the oxidation-reduction reactions on the electrode proceed highly efficiently, the enzyme electrode can cause to increase the obtained output of electric energy and thus can be suitably used in all types of fuel cells, biosensors, and electronic apparatuses. |
