ABSTRACT:
A gas component detector has a detector element of a metal oxide held on one end of a ceramic body. The detector element is electrically connected to a pair of electrodes and the pair of electrodes are in turn welded to a pair of sub-lead-lines to deliver a detected electric signal from the detector element. The pair of electrodes and sub-lead-lines are inserted in a pair of through holes of the ceramic body and the pair of electrodes are fixed by an inorganic adhesive within the through holes. The openings of the pair of through holes of the ceramic body at the opposite end with respect to the detector element are closed by a sealing material of an electrically insulating metal oxide.
