Zusammenfassung:According to one embodiment, a method is used for diagnosing a deterioration of a utility pole (10) having at least one bolt (11) and a plurality of holes (12) provided for attaching the bolt (11) . In the method, an impact is applied to the bolt (11) . Elastic waves generated due to the impact are detected by a sensor (2) shaped like a bolt. The sensor (2) is attached to at least one of the holes (12). A propagation situation of the elastic waves in the utility pole (10) is derived, based on the elastic waves detected, and each position of the bolt (11) and the sensor (2).
