The strange vector form factors are evaluated for $Q^2=0$ and $Q^2=1\ \mbox{ GeV}^2$ in the framework of the SU(3) chiral quark-soliton model (or semi-bosonized SU(3) Nambu-Jona-Lasinio model). The rotational $1/N_c$ and $m_s$ corrections are taken into account up to linear order. The mean-square strange radius $\langle r^{ 2}\rangle^{ Sachs}_{ s}=-0.35\; \mbox{ fm}^2$ and the strange magnetic moment $\mu_s = -0.44\;\mu_N$ are obtained. The results are compared with several different models.
