PROBLEM TO BE SOLVED: To provide an apparatus that generates an electromagnetic wave which is a transverse wave of a fine wavelength of a terahertz wave or more that brings a person into a favorable condition, and can be readily used by many people.SOLUTION: A recording and reproducing apparatus 20 can record an electromagnetic wave 10 which is a transverse wave of a fine wavelength of a terahertz wave or more, and reproduce it repeatedly. When it is used, it is placed near a diseased part and a part in a bad condition, or pressed against such parts for several minutes, in other words, the electromagnetic wave 10 is emitted toward inside the body of a patient 30 from outside the body of the patient 30.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】人体を良好な状態にするテラヘルツ波以上の細かい波長の横波である電磁波を発生させる装置であると共に、多くの人が手軽に使用できる装置を提供する。【解決手段】録音再生装置20は、テラヘルツ波以上の細かい波長の横波である電磁波10を記録し、繰り返し再生可能なことを特徴とする。使用の際には、病や不調の部分に数分間の間、接近、又は押し当てる、言い換えるならば、患者30の体の外側から患者30の体内に電磁波10を放射する。【選択図】図1
