PROBLEM TO BE SOLVED: To provide a sensible pad device which enables a patient to singly and easily check whether electric potential is applied or not, or a potential therapeutic device provided with the sensible pad device.SOLUTION: A touch member 1111 and an opposite installation member 1113 have a predetermined interval therebetween. Consequently, when a patient (a person having electric potential (AC waveform) for potential therapy applied thereto) touches the touch member 1111 of a sensible pad device 111, the charge amount (surface charge) of the touch member 1111 is varied, which varies a force (Maxwell stresses) operating between with the opposite installation member 1113. This causes vibration and the patient can feel, with the vibration, that the electric potential (AC waveform) is being applied to him or her.COPYRIGHT: (C)2015,JPO&INPIT【課題】被治療者が単独で簡便に電位印加の有無の確認をすることが可能な体感パッド装置又はこれが備えられた電位治療器の提供。【解決手段】タッチ部材1111と対向設置部材1113とを所定間隔をおいて設けることにより、被治療者(電位治療のための電位(交流波形)が印加されている者)が体感パッド装置111のタッチ部材1111に触れる事で、タッチ部材1111の帯電量(表面電荷)が変動し、これによりタッチ部材1111と対向設置部材1113との間に働く力(Maxwell の応力)も変動するため、振動が発生し、被治療者は自己に電位(交流波形)が印加されていることを、当該振動によって体感することができる。【選択図】図2
