PROBLEM TO BE SOLVED: To prolong life of a battery, and to back up one stimulator even when the other stimulator becomes impossible to be used. SOLUTION: First and second neurostimulators have: power supply sections; and stimulus signal generation sections which generate stimulus signals by power to be supplied from the power supply sections. Then, the first and second neurostimulators are connected to each other by an electrode lead, and neural stimulus signals from each neurostimulator are supplied to the electrode lead. The electrode lead is covered with a lead body consisting of insulating materials, and at least one stimulus electrode is provided on the lead body. Then, when the first neurostimulator falls into a situation such as lack of the remaining battery level, such a state is taken over to the second neurostimulator, and smooth shift of neural stimulation is performed.
