PROBLEM TO BE SOLVED: To provide comprehensive technology including a hydrogen-generating function, EMS (Electric Muscle Stimulation) function, and iontophoresis function in a single device.SOLUTION: A hydrogen-generating device with iontophoresis EMS is used in a whole-body bath, foot bath, and hand bath in expectation of health maintenance and promotion using promising antioxidant action of hydrogen, rehabilitation effect by EMS, relaxation of muscles, or beautification action by iontophoresis, and is used, with it thrown in a vessel including a bathtub filled with liquid such as bathwater. In use, an electrode part in which electrodes 2 and 3 are stored, is held in hand or sandwiched between legs, and one surface thereof is brought into direct contact with a body. It is expected that efficiency of taking hydrogen into the body may be improved by bringing the generated hydrogen into direct contact with the body. In a case of the iontophoresis using bath additive with beauty effect, the device is used, with an electrode surface (LED display surface 5) for generating the hydrogen brought into contact with a site. The electrode part coming into contact with the body retains a distance between a variable voltage applied to the electrode surface and insulation cases 1 and 4, so that those are insulated by a clearance. This configuration secures safety that no electrodes come into direct contact with the body.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】単独装置において水素発生機能、ＥＭＳ機能およびイオン導入機能を備えた複合的な技術を提供する。【解決手段】水素の抗酸化作用を期待する健康維持、促進、またはＥＭＳによるリハビリ効果を期待し、筋肉緩和、またはイオン導入で美容作用を期待し、全身入浴、足浴および手浴で使用するもので、入浴水等の液体が入った浴槽を含む容器内へ投げ込み使用する。電極２、３が収納された電極部を手に持ち、または足に挟み、片面を身体へ接触させて使用する。発生する水素を直接身体へ接触させることで、身体へ取り入れる効率が上がることが期待される。美容効果のある入浴剤でイオン導入を目的とする場合は、水素が発生する電極面（ＬＥＤ表５示面）を、部位に接触させて使用する。身体へ接触する電極部は、電極面に印加されている可変電圧と絶縁性ケース１、４との距離を保ち、空間絶縁しているため、直接身体へ電極が接触しない安全性が確保される。【選択図】図１
