  • Patent number: 10816461
    Abstract: A gas sensor includes: a gas detection unit including a light source and a detector; and a gas passage including a first end, a second end and a hollow part. The hollow part has a shape in which a cross-sectional area of a flow passage grows smaller. The gas passage includes: a member that divides the hollow part into at least a first area and a second area; a gas inflow port; and a gas outflow port. The gas flows from the gas inflow port into the hollow part, flows in the first area to arrive at the gas detection unit, and the gas located in the gas detection unit flows in the second area and flows out from the gas outflow port.
