Provided is an electrical stimulation treatment device which can be used more safely than a conventional device.A urination disorder treatment device includes a pair of body-surface electrode pads which are disposed at the back of the sacral bone of a person to be treated to supply an electrical stimulation signal from the back of the sacral bone, a stimulation signal control output circuit from which the pair of body-surface electrode pads supply the stimulation signal, a first measurement portion which is connected to the pair of body-surface electrode pads to measure electrocardiographic data of the person to be treated based on a signal of electrical activity of the heart of the person to be treated, and a control portion which is connected to the first measurement portion to control supply of the stimulation signal to the sacral bone by the pair of body-surface electrode pads based on an electrocardiographic waveform 51 measured by the first measurement portion, and, for example, where a heart rate of the person to be treated is judged to be a normal value from the electrocardiographic data, the control portion delays timing of an output pulse 58 from the pair of body-surface electrode pads so as not to be synchronized with the atrial systole P or the ventricular systole R of the electrocardiographic waveform 51.
