PROBLEM TO BE SOLVED: To provide a safe low-frequency therapy device capable of increasing a feeling of stimulation that a user has.SOLUTION: A low-frequency therapy device includes a therapy device body that can generate a current pulse, and an adhesive pad connected to the therapy device body so that the current pulse can be transmitted, which is stuck to a treatment region on the body surface of a user. The therapy device body includes a transmission part for outputting the current pulse, a control part for controlling the transmission part, and an operation part in which an instruction on the strength of the current pulse is given by an operation of the user. When the operation part is operated so that the current pulse is strong, the control part increases an output voltage to the transmission part so that an increase rate of a voltage in a low-frequency region where a feeling of stimulation imparted to the user is large is greater than an increase rate of a voltage in a high-frequency region where a feeling of stimulation imparted to the user is small in high and low ranges of the frequency of the current pulse that the transmission part can output.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2018,JPO&INPIT【課題】使用者の感じる刺激感を高めることができつつも安全な低周波治療器の提供。【解決手段】電流パルスを発生させ得る治療器本体と、該治療器本体に該電流パルスが伝達されるように接続され、使用者の身体表面の施療部位に貼り付けられる粘着パッドとを備え、前記治療器本体は、前記電流パルスを出力する発信部と、該発信部を制御する制御部と、前記電流パルスの強弱指示が使用者の操作によりなされる操作部とを備え、前記制御部は、前記操作部が強め操作された場合に、前記発信部が出力可能な前記電流パルスの周波数の高低範囲内において、使用者に与える刺激感の小さい高周波数域における電圧の上昇率よりも、使用者に与える刺激感の大きい低周波数域における電圧の上昇率が大きくなるように、前記発信部への出力電圧を上昇させる。【選択図】図8
