A gas sensor includes a sensor element. The sensor element has a solid electrolytic member, a measurement electrode, and a reference electrode. The measurement electrode is provided on the solid electrolytic member, and is exposed to a measurement gas. The reference electrode is provided on the solid electrolytic member, and is exposed to a reference gas. A heater operates for heating the sensor element. A portion of the heater contacts a portion of the sensor element. The temperature of the sensor element is increased to 300° C. by the heater in ten seconds after the start of activation of the heater.
