Experimental results of the I-V characteristics near
the superconductor-insulator transition observed for disorder-tuned
thin films are presented.
The I-V characteristics
exhibit new quasiperiodic structures as a function of the current.
The current interval, the number of the 
peaks, and
the magnetic-field dependence of the peaks are consistent with the
theoretical predictions of the resonant tunneling of a phase particle
in a tilted-cosine potential for a single Josephson junction
with small capacitance.
