A conductive pad for pain relieving and muscle training, comprises an electrode sheet electrically connected to a control unit and a conductive gel for attaching onto the human body. The conductive gel is added with a substance for pain relieving and muscle training, which is capsaicin, menthol, lidocaine, or other substitutes in an amount of 0.001% to 30% by mass. This invention has the function of increasing the blood circulation/local anesthesia by adding capsaicin, menthol, lidocaine, or other substitutes to the conductive gel, and has the effect of pain relieving and muscle training. The conductive pad that is made of the above described conductive gel can be used alone, and also be used with all of the TENS/EMS units in the market, offering a wide range of application. In addition, this invention does not require the additional heating source, simplifies the structure, and greatly reduces the manufacturing costs.
