To provide an abnormality diagnostic device and a method capable of accurately diagnosing abnormality of a railway vehicle.SOLUTION: The abnormality diagnostic device includes a learning unit and a diagnostic unit. The learning unit learns data selection conditions for selecting sensor data used for diagnosing a diagnostic object based on a model, which is generated based on sensor data of the diagnostic object in a railway vehicle. The diagnostic unit diagnoses abnormality of the diagnostic object based on sensor data satisfying the data selection conditions and a diagnostic model in which a relation between the sensor data and the abnormality of the diagnostic object is modeled.SELECTED DRAWING: Figure 1
