Zusammenfassung:	Provided is an abnormality diagnosis device capable of diagnosing an abnormality of a motor without setting many parameters. An abnormality diagnosis device (40) includes a current measuring unit (410) that measures a load current of the motor (20); a frequency analyzing unit (411) that performs frequency analysis of the load current; and a deterioration degree calculating unit (412) that calculates a degree of deterioration by adding up a preset number of intensity values from top in a preset frequency range.
