Abstract
PURPOSE:To achieve a higher reliability of connection between electrodes dispensing with a lead for connecting the electrodes, by connecting electrodes to a gas sensitive substance layer while being connected directly to an external electrode not through the lead. CONSTITUTION:Electrodes 14 and 16 are connected to a gas sensitive substance layer 6 and provided by vacuum evaporation of Au, Pt or the like, coating of a paste thereof or others. A heat-resistant insulating cover is provided on the ground of the gas sensitive substance layer 6 and the electrodes 14 and 16 to insulate them from a metal heating body 2. A lead frame 18 is welded with the heating body 2 through a external electrode in common to one end of the heating body 2 and the electrode 14 while being connected to the electrode 14 with a conducting adhesive 24. A lead frame 20 is connected to the electrode 16 with the adhesive 24 through an external electrode connected to the electrode 16. A lead frame 22 is welded with the heating body 2 through an external electrode connected to the other end of the heating body 2 while a weld section is protected with the adhesive 24. This eliminates the need for a lead to connect an electrode connected to the gas sensitive substance layer 6 to an external electrode.
