A gas sensor is equipped with a cover assembly made up of an outer cover and an inner cover in which a gas sensor element is disposed. The outer cover has an outer gas inlet and an outer gas outlet formed closer to a top end of the cover assembly than the outer gas inlet. The inner cover has an inner gas inlet formed closer to the top end of the cover assembly than the outer gas inlet. The inner gas inlet is oriented to minimize the entry of drops of water having entered along with a gas to be measured into the inner cover to avoid splashing of the gas sensor element with the water.
