PURPOSE: To stabilize a protective bell and to hold a contact conductor element, by a method wherein the contact conductor element of an electromagnetic wave treatment device is pierced through the center of the protective bell to protrude toward the bottom part of the bell body part and a surrounding band is provided so as to surround the bell body part while a holding band is connected to the surrounding band to mount a Velcro fastener to the holding band.

CONSTITUTION: A needle-like leading end part 3 slightly protrudes from the surface of the lower bottom part of a hanging bell type protective bell 5 and is formed so as to have roundness at the leading end thereof. The certain quantity of electricity is applied to a human body by a contact conductor element to give stimulation to the tissue of the human body to be treated to activate a tissue cell. The needle-like leading end part 3 at one end of the contact conductor element 1 is brought into contact with the skin of the human body at a right angle. In order to stably hold the rod-shape contact conductor element 1, said element 1 is pierced through the central part 6 of the top part of the protective bell 5 and a surrounding band 8 is mounted so as to surround the body part of the protective bell 5 in order to stably hold the bell 5 in the same manner. Further, by providing a holding band 9 having positive and negative Velcro fastener bands 91, 92 mounted to both terminals thereof to the bottom part of the surrounding band 8 in a direction opposed to each other, this protective bell is stably held to any affected part of the human body to treat the affected part for a long time.
