Zusammenfassung:An amperometric enzyme electrode for measuring the concentration of an enzyme substrate in a sample has an electrically conducting, porous electrode material (4) with an enzyme (13) immobilised or adsorbed thereon or therein. The electrode material (4) consists of a redox-inactive conductor with a conductive pigment (8'), a binder (8) which is not itself conducting, and a catalytic substance (9) finely divided therein. It is provided according to the invention that the catalytic substance (9) in the electrode material (4) is a stable oxide or oxide hydrate of a transition element of the fourth period of the periodic table of the elements, which is embedded in the redox-inactive conductor.
