The present invention of course can be freely selected energization destination by the hand operation, because it is held substantially constant without energization amount is changed by how the selection Iji, hand-type weak electricity especially the management of the voltage is facilitated It will provide a therapeutic device. The invention relates to a commercial or weak electrotherapeutic device with grip portions 2 which supply such as a battery is to face the treatment with weak current, adjusted by the control device, a long conductive to the both poles of the weak current at the tip of the grip portion 2 The antennal piece 13 projecting in parallel or bifurcated, by depositing the respective insulating members 15 to the base end portion of the two conductive antennae piece 13 is formed as a therapeutic conductive portion 14 both of the tip is exposed It was formed in an elongated an elastically deformable metal to the two conductive antennae piece 13 can be opened and closed by Width knob with an insulating member 15. .BACKGROUND【課題】ハンド操作により通電先を自由に選択できることはもちろん、その選択位地の如何により通電量が変化しなくほぼ一定に保持されるため、殊に電圧の管理が容易となるハンド式微弱電気治療器を提供する。【解決手段】商用やバッテリー等の電源が制御装置で調整した微弱電流で治療に臨ませる握り部2付きの微弱電気治療器であって、握り部2の先端に微弱電流の両極となる長い導電触角片13を並列的に又は二股状に突設し、両導電触角片13の基端部にそれぞれ絶縁部材15を被着することにより、両方の先端部が露出した治療通電部14として形成され、両導電触角片13を絶縁部材15での幅摘みにより開閉できるように弾性変形可能な金属で長尺に形成した。【選択図】図1
