<P>PROBLEM TO BE SOLVED: To provide an oxygen sensor capable of accurately and stably measuring the oxygen partial pressures of a plurality of gas routes and being achieved in compactation and cost reduction. <P>SOLUTION: The oxygen sensor includes a plurality of solid electrolyte cylindrical members 30 having electrodes arranged to the inner and outer surfaces 30b thereof and heating means 31 for uniformly heating the electrode ranges on the outer surface sides of the respective solid electrolyte cylindrical members 30. The electrode 32 on the outer surface side of each of the solid electrolyte cylindrical members 30 is constituted of the measuring electrode 55a arranged to a part corresponding to each of the heating means 31, the lead wire joint 56a protruded axially outward from each of the heating means 31 and the connection wire 57a for connecting the measuring electrode 55a and the lead wire joint 56a. <P>COPYRIGHT: (C)2008,JPO&INPIT |
