PURPOSE:To improve productivity of a limiting-current type oxygen sensor for measuring oxygen concentration in an atmosphere. CONSTITUTION:An oxygen ion conductive solid electrolyte plate 1 with a spiral spacer 3 formed on a side and electrode films 2a, 2b formed on both sides is laminated on a recess 7 of an insulator 10, and further a seal plate 4 with a heating part 6 is laminated thereon. Both plates will be fixed to each other without shift, alignment is easy and productivity can be improved due to reduction in a process and time. On the other hand, electrical conductivity between the electrode films 2a, 2b together with the heating part 6 and lead films 9a, 9b, 9c, 9d formed on the insulator 10 is provided via conductive adhesive 11a, 11b, 11c, 11d, so that electric conductivity and fixing is easily obtained, thereby improving productivity. |
