PROBLEM TO BE SOLVED: To provide a diagnostic system by which the state of a trap as an object to be diagnosed can be diagnosed in a diagnostic part having a small memory capacity. SOLUTION: An oscillation device 1 by which the control number and the diagnostic reference of the trap 3 as the object to be diagnosed are oscillated is attached to an exit-side pipe 4 in the trap 3 via a rubber band 5. By a diagnostic device 2 in which a vibration detection part 6 and the CPU (the diagnostic part) 16 are built, the control number and the diagnostic reference of the trap 3 oscillated from the oscillation device 1 and a vibration due to the operation of the trap 3 are detected, and the trap 3 is diagnosed on the basis of the detected diagnostic reference of the tarp 3 and on the basis of a detection value of the vibration due to the operation of the trap 3.
