An air-fuel ratio detecting apparatus, comprises a first pair of electrodes, interposing a porous solid electrolyte therebetween, a second pair of electrodes, interposing a porous solid electrolyte therebetween, a dense solid electrolyte to which one of the first pair of electrodes and one of the second pair of electrodes contact, and a device for causing constant-currents to flow through the first and second pairs of electrodes, respectively, so as to detect voltage developed between the electrodes contacting with the dense solid electrolyte, thereby for obtaining air-fuel ratio detecting apparatus having uniform voltage output characteristics even by mass production. |
