PROBLEM TO BE SOLVED: To provide an electric stimulator having a shorter healing time, less burden on a living body, and easy to attach. SOLUTION: A base wire comprising a core wire (21) having an insulating film and an outer wire (22) wound around the core wire as a winding shaft with no gaps is provided, and the base wire material is formed by winding the base wire in a loop shape. The core wire 21 is electrically connected to one end of the external wire 22, the other end of the core wire 21 is connected to one end of the external circuit 8, and the other end of the external wire 22 is connected to the other end of the external circuit 8. An electric stimulator 1 which is connected and gives an electric stimulus to a living body placed therein by a tubular portion.
