发明名称 Gas sensor with sealing structure
摘要 In a method of manufacturing a sensor, firstly, a plate-type detection element is inserted through an element-insertion through-hole of a first powder-compacted ring. Secondly, a flange section including at least the first powder-compacted ring is integrally assembled to the plate-type detection element, applying axially compressive pressure to the first powder-compacted ring so as to compressively deform the first powder-compacted ring such that the cross-sectional area of the element-insertion through-hole is reduced. Thirdly, the flange section is engaged, directly or via an intermediate member, with the stepped portion of the metallic shell at the time of disposing of the plate-type detection element in the through-hole of the metallic shell. A sensor prepared by the method is also disclosed.
