The degradation determining apparatus includes an antenna and a degradation determiner. The antenna receives an electromagnetic wave in the microwave frequency band emitted due to partial discharge occurring in an insulating member included in a motor, and generate a reception signal. The degradation determiner determines, based on compliance or noncompliance of the reception signal with a standard, whether any degradation occurs in the insulating member.
