Abstract
A gas sensor having a gas sensing element of which electrical resistance changes in accordance with gas components contained in sensing gas and a ceramic member for firmly holding the sensing element is fixedly mounted, in which the gas components are detected by sensing a resistance of the gas sensing element. In the gas sensor, a conductive member which is mounted to the gas sensing element, extending through the center between a pair of lead members for sensing an electrical resistance of the gas sensing element, is provided on the ceramic member or the gas sensing element, and the conductive member is connected to ground.
