In order to substitute for the marketed horseradish peroxidase, a hydrogen peroxide sensor embedded with tobacco leaf in carbon pastes was constructed and its sensing ability was electrochemically evaluated. Ten and more electrode parameters obtained implied that the enzyme electrode exerts its remarkable specificity quantitatively in the experimental range of potential. Especially the small symmetry factor (${\alpha}$, 0.21) showed that the electrode kinetics is very sensitive to the change of electrode potential. The experimental facts above suggested that our enzyme electrode functions as a hydrogen peroxide sensor normally and tobacco peroxidase can be used in the place of the marketed one as an alternative to marketed ones.
