The present invention, in the software to a biological, electrical stimulation of the inner muscles in the deeper layers muscle training, such as to provide, relaxation, shape up, and low back pain treatment, fatigue recovery treatment apparatus for generating bio-stimulation signal waveform that effectively form a signal waveform in line with the wide variety of bio-stimulation purposes, and the like, and electrical bio-stimulation the provision of equipment it is an object of the present invention. In the waveform generator for electrical bio-stimulation given to the bio-electrical stimulation by the composite wave obtained by superimposing the low-frequency pulse signal wave and the high-frequency signal wave, the high-frequency signal wave is said during the on-state of the low-frequency pulse signal wave is superimposed on the low frequency pulse signal wave, the composite wave, the level of a composite wave that is configured to gradually increase from a superimposition start point and combined in succession on and off periods of the synthetic waveform and characterized in that it is a generator.本発明は、生体にソフトで、より深層にあるインナーマッスルへの電気刺激を与えるような筋肉トレーニング、リラクゼーション、シェイプアップ、および腰痛施術、疲労回復治療など多岐に亘る生体刺激目的に即した信号波形を効果的に形成する生体刺激用信号波形の発生装置および電気的生体刺激装置の提供を課題とする。低周波パルス信号波と高周波信号波とを重畳させた合成波により電気的刺激を生体に与える電気的生体刺激用波形発生装置において、前記低周波パルス信号波のオン状態時に前記高周波信号波が前記低周波パルス信号波に重畳され、前記合成波は、そのレベルが重畳開始時点から徐々に上昇するように構成された合成波であり、該合成波のオン・オフ周期を連続して組み合わせた波形発生装置であることを特徴とする。
