摘要： An air-fuel ratio sensor comprises an oxygen concentration sensing element, a housing for holding this oxygen concentration sensing element, and protecting covers with gas holes. The protecting covers comprises an inside cover disposed closely to the oxygen concentration sensing element, and an outside cover surrounding the outside cover. Flange-like peripheral portions, formed on the protecting covers, are fixed to the abutting face of the housing by a caulking operation. These flange-like peripheral portions are disposed alternately along a same closed curve around the oxygen concentration sensing element, so that they are not overlapped with each other.

摘要： An oxygen sensor 3 having a heater 2 capable of providing an improved temperature increasing characteristic, while maintaining an increased amount of introduced air and a high production efficiency. The sensor 3 includes a sensor element 1 having an air chamber 100 in which a heater 2 is arranged. The heater 2 has a rectangular cross sectional shape. In order to produce the heater 2, onto a green ceramic sheet, a heater of a predetermined pattern including a plurality of heater sections is printed. Then, to the printed sheet, different ceramic green sheets are applied so as to obtain a laminated body. The laminated body is subjected to a cutting so as to produce an intermediate body in which a heater section is included. The intermediate body is subjected to a firing to obtain a completed heater.

摘要： An improved structure of a gas sensor is provided which includes a hollow housing and a sensing element. The sensing element has a flange and is disposed within the housing in engagement of the flange with an inner wall of the housing. An insulating powder is packed in a chamber defined by the inner wall of the housing, the flange and an outer wall of the sensing element to provide an air-tight seal between an air chamber to which one end of the sensing element is exposed and a gas chamber to which the other end of the sensing element is exposed. The air-tight seal has the structure designed to minimize an air leakage and breakage of the sensing element when installed in the housing.
