PROBLEM TO BE SOLVED: To provide an electrochemical type gas sensor in which continuity of a work electrode and a conductor wire is not easily released.SOLUTION: The sensor stores a work electrode 21, a reference electrode 22, a counter electrode 23 and electrolytic solution contacting with the electrodes 21-23 in a housing, and has a plurality of conductor wires 60 individually connected to each of the work electrode 21, the reference electrode 22 and the counter electrode 23. At least part of a contact area of the work electrode 21 and a conductor wire 60 connected to the work electrode 21 is located to be pressed by a pressing member when seen from a top view, while a contact area of the reference electrode 22 and a conductor wire 60 connected to the reference electrode 22 is not located to be pressed by the pressing member when seen from the top view. |
