PROBLEM TO BE SOLVED: To provide the sensitivity tester of a fire sensor, which can shorten time required for the sensitivity test of the fire sensor, compared to a conventional one, when the scale of fire warning facility is enlarged. SOLUTION: Plural measuring bases B1-B4 to which fire sensors as inspection objects are fitted and one test circuit testing the plural fire sensors fitted to the plural measuring bases B1-B4 are installed. In a sensitivity tester, the test circuit has a signal switch means changing over an output signal which the fire sensor outputs through the plural measuring bases B1-B4 and taking it into the test circuit.
