Constant potential electrolytic gas sensor and method for manufacturing constant potential electrolytic gas sensor

A method for manufacturing a constant potential electrolytic gas sensor, the constant potential electrolytic gas sensor comprising:

• a case with a case body;
• an electrode structure comprising at least two electrodes provided in the case body;
• at least two lead wires that extend along respective surfaces of the at least two electrodes and are connected to the respective surfaces of the at least two electrodes;
• and
• at least two external electrodes that extend from the outside of the case to the inside of the case, are provided in the case body, and are connected to the at least two lead wires, respectively,
• wherein the method comprises the steps of:
• introducing the lead wire along an introduction path from the outside of the case body toward the electrode structure via a connection point of the external electrode;
• arranging the lead wire between the surface of the electrode and the connection point of the external electrode;
• and
• connecting the lead wire to the external electrode at the connection point of the external electrode with the lead wire being arranged on the surface of the electrode.
