PROBLEM TO BE SOLVED: To provide an electric therapeutic instrument capable of improving a user's convenience in executing operation to change electric stimulation strength.SOLUTION: An electric therapeutic instrument includes a plurality of electrodes brought into contact with sites of a user's body, an operation part for receiving operation to adjust strength of electric stimulation applied to the sites, and a voltage control part for treating the sites by discretely changing a voltage applied to the plurality of electrodes according to the operation. The voltage control part changes the applied voltage by a first amount of change according to the operation until the strength of electric stimulation reaches predetermined strength of stimulation, and changes the applied voltage by a second amount of change which is smaller than the first amount of change according to the operation after the strength of electric stimulation reaches the predetermined strength of stimulation.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】電気刺激強度を変化させる操作を行なう際のユーザの利便性を向上させることが可能な電気治療器を提供する。【解決手段】電気治療器は、ユーザの身体の部位に接触される複数の電極と、部位に与えられる電気刺激強度を調整するための操作を受け付ける操作部と、操作に応じて、複数の電極への印加電圧を離散的に変化させることにより部位の治療を行なう電圧制御部とを備える。電圧制御部は、電気刺激強度が所定刺激強度に到達するまでは操作に応じて印加電圧を第1変化量で変化させ、電気刺激強度が所定刺激強度に到達した後は操作に応じて印加電圧を第1変化量よりも小さい第2変化量で変化させる。【選択図】図1
