The fixing force evaluation method of the present embodiment includes the natural frequency measurement step of measuring the natural frequency of the stator in which the tooth portions and the stator coil are fixed by the insulating paper, and the fixing force evaluation step of evaluating that the fixing force of the insulating paper is larger, when the natural frequency of the stator measured in the natural frequency measurement step is equal to more than a predetermined determination frequency, compared to when the natural frequency is lower than the determination frequency. Thus, since the fixing force of the insulating paper is evaluated in the fixing force evaluation step based on the natural frequency of the stator measured in the natural frequency measurement step, the fixing force of the insulating paper can be evaluated by measuring the natural frequency of the stator without destroying the stator.
