  Let $s_0 < 0$ be the abscissa of absolute convergence of the dynamical zeta
function $Z(s)$ for several disjoint strictly convex compact obstacles $K_i
\subset \R^N, i = 1,..., \kappa_0,\: \ka_0 \geq 3,$ and let $R_{\chi}(z) = \chi
(-\Delta_D - z^2)^{-1}\chi,\: \chi \in C_0^{\infty}(\R^N),$ be the cut-off
resolvent of the Dirichlet Laplacian $-\Delta_D$ in $\Omega = \bar{\R^N
\setminus \cup_{i = 1}^{k_0} K_i}$. We prove that there exists $\sigma_1 < s_0$
such that $Z(s)$ is analytic for $\Re (s) \geq \sigma_1$ and the cut-off
resolvent $R_{\chi}(z)$ has an analytic continuation for $\Im (z) < -
\sigma_1,\: |\Re (z)| \geq C > 0.$
