Abstract: A gas sensor including an adjustment unit having a conversion element for converting a gas component contained in exhaled breath introduced into a first chamber to a particular component, a sensor unit having a second chamber and including a detection element, a ceramic wiring board electrically connected to the detection element, and a single heater for heating the conversion element and the detection element. The ceramic wiring board has an opening, and a ceramic thin plate is stacked on the ceramic wiring board to cover the opening. The ceramic thin plate partially constitutes the adjustment unit and the sensor unit and separates the first chamber and the second chamber from each other. The adjustment unit, the sensor unit, and the heater are integrated in such a manner that the adjustment unit and the sensor unit are thermally coupled through the ceramic thin plate.
