  The data of type Ia supernovae observed by the High-z SN Search Team and
Supernova Cosmology Project are analyzed in inhomogeneous cosmological models
with a local void on scales of about 200 Mpc, to derive the best-fit values of
model parameters and the confidence contours. The $\chi^2$ fitting is found to
be slightly better than that in homogeneous models. It is shown that (1) the
best-fit values are most sensitive to the ratio $R$ of the outer Hubble
constant ($H_0^{\rm II}$) to the inner Hubble constant ($H_0^{\rm I}$), (2) the
best-fit outer density parameter ($\Omega_0^{\rm II}$) (and cosmological
constant parameter ($\lambda_0^{\rm II}$)) increases (and decreases) with the
increase of $R$, respectively, and (3) $(\Omega_0^{\rm II}, \lambda_0^{\rm
II})$ can be $(1, 0)$ for $R \approx 0.8$. Moreover it is shown that these
models may be naturally consistent with the new supernova data (SN1997ff) for
$z = 1.7$.
