A plate-shaped detection element is inserted into the casing and has one end protruding outside the casing to detect external oxygen concentration, and a plate-shaped detection element is arranged in the casing at a distance from each other and one end is connected to the detection element. A heat-resistant talc layer and a glass layer are filled in the casing so as to cover the area from each lead plate to the detection element, and are sintered in the casing. In the oxygen sensor, a platinum-supported ceramic layer is provided between the talc layer and the glass layer in order to capture carbon in the exhaust gas that enters the talc layer from one end side of the casing. sensor.
