摘要： To provide a gas sensor apparatus capable of preventing clogging of a gas intake port due to particles, droplets, or the like, of a gas and maintaining measurement accuracy for a long time, a gas sensor apparatus 1 includes a housing 3. The housing 3 includes an expansion chamber 6 communicating with an air intake passage 2 via an air intake port 8, and a measurement chamber 5 communicating with the expansion chamber 6 via a communicating portion 7. A double squeezing structure including the gas intake port 8 and the communicating portion 7 is provided, and two stages of regions where the volume expands between the gas intake port 8 and the measurement chamber 5 are provided. As a result, the movement of the air in the measurement chamber 5 is decreased. It is possible to provide a structure in which the capacity of the gas intake port 8 is increased to avoid clogging of the gas intake port due to particles or droplets.
