PROBLEM TO BE SOLVED: To ease pains in a wide range of an organism and a narrow range within the wide range.SOLUTION: A stimulation circuit supplies electric stimulation signals to between at least one of stimulating electrodes of a first electrode lead 2A and at least one of stimulating electrodes of a second electrode lead 2C. In parallel with this, a stimulation circuit supplies electric stimulation signals to between stimulating electrodes of a third electrode lead 2B within the area formed by at least one of the stimulating electrodes of the first electrode lead 2A and at least one of the stimulating electrodes of the second electrode lead 2C, which supply the electric stimulation signals.COPYRIGHT: (C)2015,JPO&INPIT【課題】生体の広範囲とその広範囲内の狭範囲の疼痛の緩和を行う。【解決手段】刺激回路は、第1の電極リード2Aの少なくとも1つの刺激電極と第2の電極リード2Cの少なくとも1つの刺激電極の間に電気的刺激信号の供給を行う。これと並行して、刺激回路は、該電気的刺激信号の供給を行う第1の電極リード2Aの少なくとも1つの刺激電極と第2の電極リード2Cの少なくとも1つの刺激電極により形成された領域内の第3の電極リード2Bの刺激電極の間に電気的刺激信号の供給を行う。【選択図】図10
