Abstract(in English) We investigated oscillation characteristics of stacked Bi-2212 intrinsic Josephson junctions for various size (S=17×145~17×20μm^2,N=65~200)fabricated by dilute acid solution (pH=1.65). At 77 K, zero voltage current for the detector stacks was measured while sweeping a bias voltage of the oscillator stack. The zero voltage current of the detector stack was strong suppressed when kink structure in current-voltage curve of the oscillator stacks were observed. We found that the observed characteristics were explained by the cavity resonance and the cavity mode is dependent on the number of junctions in stack.
