An electric stimulation device includes a main body portion having a stimulation electrode stimulating nerves or muscles inside the living body, a stimulation circuit portion with a stimulation circuit electrically connected to the stimulation electrode and applying a stimulation signal to the stimulation electrode, and a support body connected to the stimulation circuit portion and holding the implant position of the stimulation electrode inside the living body. The electric stimulation device also includes a fixing body connectable to the base end portion of the main body portion. The fixing body includes a fixing body side coil portion that receives an electromagnetic wave transmitted from an external device. When the fixing body is connected to the main body portion, the fixing body side coil portion is electrically connected to the stimulation circuit to enable power feeding and/or communication with respect to the stimulation circuit in response to the electromagnetic wave.
