Abstract

PROBLEM TO BE SOLVED: To provide a director for a low frequency curing device which is reduced in side, as a good temperature rising characteristic and is so flexible as to have high adhesiveness to the human body. SOLUTION: When heater electrodes 12a, 12b are connected to a power supply to apply designated voltage, an electric current flows between the electrodes 2a, 12b through a conductive elastomer 14, and heat is generated in the conductive elastomer 14 to warm a director device for a low frequency curing device. Then, when the director 10 for the low frequency curing device is brought into contact with a lesion to apply designated low-frequency current to a body applying electrode 13, the current is applied to a gel layer 17 from an opening part of an insulating film 15 through a conductive carbon 16. Accordingly, a low-frequency current is applied to the body which is in contact with the gel layer 17. As the heater electrodes 12a, 12b and the body applying electrode 13 are formed on the same base film 11, it is sufficient to provide one electrode layer and the layer can be made thin.
