| description | An object of the present invention is to provide an apparatus for evaluating a response time of gas sensors, which can improve evaluation accuracy of a response characteristic time of the gas sensors while simulating the actual use environment of the gas sensors. The apparatus for evaluating a response time of gas sensors includes: a pipe (2); a first gas supplier (3) for supplying a first gas (3a) to the pipe; a second gas adding machine (5) for adding a second gas (5a-5c) to the first gas in the pipe; and gas sensors (1) for detecting components in a mixed gas of the first gas and the second gas, each of the gas sensors being attached to the pipe on a downstream side of an addition position of the second gas in a flow direction of the first gas. The second gas adding machine includes: a supply source (50, 53, 56) of the second gas; a connecting pipe (51, 54, 57) for connecting the supply source to the pipe; and a connecting pipe on-off valve (52, 55, 58) for opening and closing the connecting pipe.
