　The soft heating method, which is one of the heating methods of hyperthermia, is a safe heating method that can control the attainable temperature of the heating element by using the Curie temperature of the magnetic material. As the heating element, we have proposed an LC booster-type heating element in which a thermosensitive magnetic material, a metallic ring, and an LC resonator are arranged in this order toward the outside. However, in this configuration, the coil conductor of the LC resonator part is exposed to the living tissue, and it is not suitable for implanting in the body. To solve the problem, we suggest the element of new configuration reversing the arrangement of the metallic ring and the LC resonator. In this study, we made a prototype to confirm the characteristics of power consumption and temperature profile with changing number of turns. As a result, we could clarify the heating characteristics of the element.
