PROBLEM TO BE SOLVED: To effectively shield an input coupling of a heater voltage and prevent errors in measurement signals by a simple means by improving an electrochemical sensor. SOLUTION: An electrochemical sensor has a solid electrolyte which includes at least one first electrode, at least one second electrode and at least one heater element. An electrode 13 closest to a heater element 17 is grounded, and a different electrode 12 cooperating with the electrode 13 has a negative polarity. |
