Abstract
A gas sensor for detecting a predetermined gas component in a measurement gas includes a sensor element in which an opening of a first gas inlet and an opening of a second gas inlet for introducing the measurement gas from an outside are provided at one end. The openings are elongated and substantially rectangular. A sum of sizes in a lateral direction of the openings is greater than or equal to 8 μm and less than or equal to 60 μm, and a sum of areas of the openings is greater than or equal to 0.02 mmand less than or equal to 0.1 mm. The sizes in the lateral direction and the areas of the openings are set to be within a preferable range so that the water droplets attached on the forward end surface can be prevented from entering into the sensor element through the openings.
