Abstract
An inspection apparatus capable of performing responsivity inspection on a plurality of gas sensors at equivalent accuracies is provided. The inspection apparatus includes a plurality of inspected sensor disposing parts that are provided halfway through one gas flow path at equal intervals in an extending direction of the flow path and in each of which a gas sensor to be inspected is disposed, and a plurality of straightening plates provided upstream of each of the inspected sensor disposing parts on the gas flow path and separated at a constant distance from the inspected sensor disposing parts. The straightening plates each include a rectangular opening orthogonal to the gas flow path and open to the gas flow path. When the gas flow path extends in one direction in a horizontal plane, the opening has a longitudinal direction along a direction orthogonal to the one direction in the horizontal plane.
