We perform tunneling spectroscopy of Sr$_2$RuO$_4$ searching for the edge
states peculiar to topological superconductivity. Conductance spectra obtained
on Sr$_2$RuO$_4$/Au junctions fabricated using $in$ $situ$ process show broad
humps indicating the successful detection of a-axis edge of 1.5K phase. Three
types of peak shape are detected: domelike peak, split peak and two-step peak.
By comparing the experiments with predictions for unconventional
superconductivity, these varieties are shown to originate from multiband chiral
p-wave symmetry with weak anisotropy of pair amplitude. The broad hump in
conductance spectrum is a direct manifestation of the edge state peculiar to
the chiral p-wave superconductivity.
