Claims

[Scope of utility model registration request]

an element body made of a cylindrical oxygen ion permeable solid electrolyte with electrodes formed on its inner and outer surfaces and closed at one end; a tubular heater inserted and held within the element body; and a tubular heater fitted into the opening of the element body. A holding member for holding the holding member, a heat insulating material for pressing the holding member toward the element body side, and resilient means such as a spring, which are fitted onto the outer periphery of the heat insulating material and resilient means, and are connected to the element body. an inner cylinder that is held integrally with the main body;
An oxygen concentration detector comprising: an outer cylinder further provided on the outer periphery of the inner cylinder with a heat insulating layer such as air or a heat insulating material sandwiched therebetween.
