PROBLEM TO BE SOLVED: To provide a measuring object characteristic measuring device capable of miniaturizing the device, preventing attenuation of an elastic surface wave, and maintaining measurement accuracy. SOLUTION: In this measuring object characteristic measuring device 10 equipped with an elastic surface wave element 14 wherein a short-circuit propagation path 34 to be loaded with a measuring object 40 is formed between an input electrode 30 and an output electrode 32, a burst wave signal is input from an input terminal 42 to the input electrode 30, and a characteristic of the measuring object 40 is determined based on an output signal output from the output electrode 32 to an output terminal 44, by having a first switcher 24 and a second switcher 26. In the measuring object characteristic measuring device 10, the short-circuit propagation path 34 is shortened, and thereby miniaturization becomes possible as a measuring device for measuring a physical characteristic of the measuring object 40 having low conductivity.
