According to the present invention, the selectivity, sensitivity, reaction rate and recovery rate of the reaction gas are improved by optimizing the types of the working electrode, the reference electrode, the counter electrode, and the electrolyte depending on the kind of the reaction gas (toxic gas) And a method of manufacturing the electrochemical sensor. According to the present invention, it is possible to realize an electrochemical sensor having selectivity to a toxic gas and high sensitivity and high responsiveness, thereby enabling to operate a safe and stable production line of an operator in an industrial environment, Can safely protect the lives of people and ensure stable production. |
