PROBLEM TO BE SOLVED: To provide a simple behavior abnormality detector which diagnoses abnormality of a behavior expressed by three-axis acceleration, angular velocity and velocity by utilizing characteristic of a moving body repeating the same action. SOLUTION: A behavior sensor 11 measures the behavior of the moving body, starts behavior measurement when a position detector 16 detects a time at which the moving body enters a measurement area on a moving path, and transmits behavior data to a behavior analyzer 14 when detecting a time of leaving of the moving body. The behavior analyzer 14 generates judgment data using the behavior data of the moving body accumulated in a storage device 13, and stores it in the storage device 13. When detecting abnormality of the behavior by comparing the behavior data of the moving body in the measurement area with the judgment data, the behavior analyzer 14 causes an alarm to be generated. The judgment data is formed as a threshold of detecting the abnormality of the behavior by statistically processing the set of behavior measurement values collected while the moving body passes through the measurement area more than once.
