Abstract
An enzyme electrode comprising an enzyme and a coenzyme immobilized in at least one layer is provided. This electrode has an outer membrane preventing the coenzyme from dissipation and so sensitivity and durability can be improved. In an inner membrane containing the enzyme and the coenzyme, a mediator of electron transfer may be added. The enzyme and the coenzyme may be separated in two layers, respectively, in the inner membrane to improve measurement sensitivity.
