Disclosed is a treatment device for urination disorders, said treatment device being capable of determining whether or not stimulation-applying electrodes are appropriately arranged and whether or not nerves that control urine accumulation and urination are being appropriately stimulated. The disclosed treatment device can therefore provide appropriate treatment for urination disorders. The treatment device is provided with: at least one pair of stimulation-applying electrodes that apply a stimulation signal to the dorsal surface of the sacrum； a stimulation-signal source that supplies the stimulation signal applied by the stimulation-applying electrodes； a stimulation-transmission detection electrode that is disposed near tissue connected to nerves that run near the sacrum or to the sacrum, and that detects a biosignal that arises in response to the stimulation signal； a ground electrode； a measurement unit that measures the biosignal detected by the stimulation-transmission detection electrode； a control unit that controls the application of the stimulation signal by the pair of stimulation-applying electrodes； and a display means that displays the measurement result from the measurement unit.
