PURPOSE:To obtain a compact blood circulation promoting apparatus hardly generating the damage of an antenna part and easy to use, by arranging an antenna to one side surface of a substrate having rigidity while arranging a battery to the other side surface thereof and arranging a circuit around the battery on the same side surface as the battery of the substrate. CONSTITUTION:An antenna 23 is formed into a vortex shape so as to surround both charge terminals 20, 21 provided to the central part of a printed circuit board 10. By this structure, the antenna 23 can be provided long by utilizing the considerably wide space on the printed circuit board 10 and, therefore, large output can be obtained by the same current quantity as conventional one. Conversely speaking, smaller power may be used in order to obtain the same output and, therefore, power can be conserved and the life of a battery becomes long. As mentioned above, since the antenna 23 is arranged on the side of a mount surface and extremely thinly formed along with the charge terminals 20, 21 by printing technique, an electromagnetic field can be allowed to efficiently act on the affected part from a position close to the skin surface 30 of the body. |
