Abstract
A drainage structure for a gas sensor includes a detection element, a protector, and a drainage. The detection element is held in a housing. The detection element includes a detector that is provided in a tip end. The detector is configured to detect a specific component in gas of interest by contact of the gas of interest with the detector. The protector is secured to the housing. The protector covers the detector while ventilation is kept. The drainage has a long shape and is mounted to the protector. The drainage includes a first end disposed in the protector and a second end disposed outside the protector. The drainage is configured to produce a capillary action.
