PROBLEM TO BE SOLVED: To provide an electron mediator that can obtain a response current value compared to the conventional art.SOLUTION: The present invention provides an enzyme electrode comprising an electrode, and a reaction layer that contacts the electrode and comprises an enzyme and a mediator, wherein electronic exchange is performed through the mediator between the enzyme and the electrode in the reaction layer. In the enzyme electrode, as the mediator, used is cytochrome C protein derived from microorganisms having catabolic metal reduction ability.SELECTED DRAWING: Figure 1 【課題】従来品よりも高い応答電流値が得られる電子メディエータを得ること。【解決手段】電極と、前記電極と接触し、酵素とメディエータとを含む反応層とを含み、前記反応層における前記酵素と前記電極との間で前記メディエータを介して電子授受が行われる酵素電極において、前記メディエータとして、異化的金属還元能を有する微生物由来のシトクロムＣ蛋白質を用いることを特徴とする、酵素電極。【選択図】図１
