ABSTRACT:
According to the present invention, an oxygen concentration detector includes a housing, a detecting element inserted into said housing and a cover for covering a top portion of said detecting element. The detecting element is made of solid electrolyte and includes an atmospheric chamber therein. The cover includes an air vent portion for introducing air into said atmospheric chamber of the detecting element. The detecting element includes an air introducing path open to the atmospheric chamber at a side wall of the detecting element. It is possible to provide an oxygen concentration detector capable of introducing the air into the atmospheric chamber and maintaining an oxygen concentration in the atmospheric chamber at the same level as an atmosphere constantly.
