    摘要： The sensor element 110, which can detect the concentration of a specified gas, is held with a housing 102 with a front end thereof exposed. A protective cover 120 includes an inner cover 130 and an outer cover 140, and secured to the housing 102. A ratio φ1/φ2 is set to a range from 0.6 to 0.9, where φ1 represents an outer diameter of a portion where an inner gas aperture 134a is formed in the inner cover 130, and φ2 represents an inner diameter of a portion where an outer gas aperture 144a is formed in the outer cover 140.

    摘要： A gas sensor, that represses a manufacturing cost, obtains high responsiveness and can effectively reduce adhesion of water to a sensor element and intrusion of water into the sensor element, is provided. In the gas sensor that has the sensor element mainly containing a solid electrolyte with oxygen ion conductivity and a protective cover arranged to surround the sensor element and detects a predetermined gas component in a measurement gas, the protective cover includes an inner protective cover that is formed into a bottomed cylindrical shape, has a plurality of inner gas distributing holes formed in two rows on its side surface in a longitudinal direction of the sensor element and surrounds one front end of the sensor element, and an outer protective cover that is formed into a bottomed cylindrical shape, has a plurality of outer gas distributing holes on its side surface and surrounds the inner protective cover.
