Abstract (in Japanese) (See Japanese page) 
(in English) Recently, circulating tumor cell (CTC) is gathering attention because the clinical applications are enabled by investigating the condition of the CTC. Our group has researched the CTC detection device by using the ring-resonator type of electrode and measuring the resonant frequency by inherent dielectric constants. In this paper, the Q-factor of ring-resonator type of electrode was considered to improve detection sensitivity by setting the negative resistance on this electrode and controlling the resistance values. As the negative resistance, a usefulness of the Esaki diode and the FET combined with the capacitance were examined on the circuit simulation. Furthermore, the simple ring-resonator type of electrode connected with the FET as the negative resistance was fabricated as the early research, and the resonant frequency for each material was measured in order to investigate the ability of this electrode. From the result, it was confirmed that the resonant frequency was separated at MHz order and the detection sensitivity was increased due to enhancement of the Q-factor by using the negative resistance.
