PROBLEM TO BE SOLVED: To provide a smoke detector sensitivity test device for much more accurately testing the sensitivity of a smoke detector. SOLUTION: When a smoking operation is started by a smoke generator 4 (a step #3), the measurement of smoke concentration is started by a smoke concentration measuring unit 6, and smoke concentration data showing the smoke concentration measured with fixed time intervals are acquired from the smoke concentration measuring unit 6, and stored in a storage part 22 in a control part 20 (a step #4). When an alarm signal is outputted from a smoke detector 100 (a step #5; YES), a display control part 24 reads the smoke concentration data a delay time T before this point of time (the alarm signal has been received), that is, when the smoke detector 100 decides that the smoke concentration exceeds a threshold, and started the output of a pulse from the storage part 22 (a step #6), and makes an LCD 9 display the smoke concentration concerned with the smoke concentration data.
