  We investigate a topological inflation model in supergravity. By means of
numerical simulations, it is confirmed that topological inflation can take
place in supergravity. We also show that the condition for successful inflation
depends not only on the vacuum-expectation value (VEV) of inflaton field but
also on the form of its K\"ahler potential. In fact, it is found that the
required VEV of the inflaton $\phi$ can be as small as $<\phi > \simeq 1 \times
M_G$, where $M_{G}$ is the gravitational scale.
