  In the present invention, a Peltier element having a Peltier effect is used as the thermoelectric element 700. Here, the Peltier effect refers to a phenomenon in which one terminal absorbs heat and the other terminal generates heat when a current is applied to the end after connecting two kinds of metal ends. When semiconductors such as bismuth (Bi) and tellurium (Te) having different electric conduction methods are used in place of the two kinds of metals, a Peltier element that performs highly efficient heat absorption and heat generation can be obtained. This can switch heat absorption and heat generation according to the direction of the current, and can adjust the heat absorption amount and the heat generation amount based on the current amount. In the present invention, a Peltier element is utilized as a thermoelectric element.

The control unit 920 is preferably configured to control the supply of power and the driving of the cooling fan 800 so that the ceramic pad 710 maintains a constant temperature range within a preset temperature range. That is, the controller 920 detects the temperature of the ceramic pad 710 that conducts heat to the thermoelectric element 700, and the controller 920 supplies and cools the power so that the ceramic pad 710 can maintain a preset temperature based on the detected temperature. The drive of the fan 800 is controlled. Thereby, the ceramic pad 710 can be maintained at a constant temperature. Accordingly, the temperature of the electrode unit 700 attached to the lower surface of the ceramic pad 710 is always kept constant.

At this time, a high frequency of 13.56 MHz generates heat while passing through the tumor site. Therefore, using a high frequency of 13.56 MHz that is particularly sensitive to cancer cells, heat of 42 degrees Celsius that is sensitive to the tumor is selectively applied only to the cancer tissue by a non-invasive energy control method. This can directly induce tumor necrosis or death to activate metabolism and the immune system. Therefore, the present invention is also effective for cancers that are deep in the depth, such as pancreatic cancer. Normally, cancer has a property of infiltrating into a tissue, and therefore a higher thermal effect (that is, a therapeutic effect) can be expected by emitting a high frequency from both sides centering on the cancer tissue.
