PROBLEM TO BE SOLVED: To miniaturize an external feeder system for supplying power to an electric stimulator. SOLUTION: The electric stimulator is equipped with a body block including a stimulation electrode for stimulating nerves etc., an electronic circuit for applying stimulation signals to the stimulation electrode, a stimulation circuit block with a power source part for feeding power to the electronic circuit, and a support body holding an implanting position of the stimulation electrode in a living body, wherein at least a lumen is formed in the support body, The electric stimulator includes two or more first electrical contact points placed in a lumen and electrically connected to the power source part, and further, a power receiving coil part which generates power by electromagnetic waves from external equipment and a coil lead part including a body with two or more second electrical contact points electrically connected to the power receiving coil part. When the body is inserted into a lumen, the first and second contact points are connected to electrically connect the power source part and the power receiving coil part. COPYRIGHT: (C)2011,JPO&INPIT
