ABSTRACT:
To provide a gas sensor in which connection terminals are stably brought into contact with electrode terminal portions of a sensor element without superfluous load applied on the sensor element. A pair of element guide portions33are provided in a sleeve30in which a plate-like sensor element10is inserted. The pair of element guide portions33protrude from an opening end surface on a rear end side of an axial hole31, store either of widthwise opposite side ends of the sensor element10and restrain the sensor element10from being inclined. The sensor element10is positioned coaxially with the sleeve30by the element guide portions33. Electrode holders40in which electrode fitments60are held are fitted to the element guide portions33so that the electrode fitments60are brought into contact with electrode terminal portions15and16of the sensor element10. Because the positional relation between the two is decided on the basis of the element guide portions33, there is no superfluous load applied on the sensor element10, so that the sensor element10is prevented from being broken. In addition, pressure of contact of the electrode fitments60with the electrode terminal portions15and16of the sensor element10is kept substantially constant, so that electrically stable connection can be obtained.
