PROBLEM TO BE SOLVED: To provide a gas sensor which can achieve further reduction in a wasted area of a filter.SOLUTION: A vent hole 31a and a vent hole 32a are not arranged in a manner to face each other. In comparison with a conventional way that vent holes are arranged in a manner to face each other, a larger area of a filter 5 can be used because the outside air flowing through the vent hole 31a to the filter 5 passes through a large area inside the filter 5. As a result, a wasted area of the filter 5 can be further reduced. |
