Transport properties are systematically studied for the single crystals Cu$_{x}$TiSe$_{2}$ (0.015$\leq$x$\leq$0.110). Both of in-plane and out-of-plane resistivity show the coexistence of superconducting transition and charge density wave (CDW) for the single crystals with $x \leq 0.025$. After CDW state is completely suppressed around x=0.055, the superconductivity is apparently enhanced by Cu doping. No superconducting transition is observed above 1.8 K for Cu$_{0.11}$TiSe$_{2}$. Anisotropy in resistivity increases with increasing Cu content, and is nearly $T$-independent. CDW state has a strong effect on Hall coefficient and thermopower. A large thermopower, comparable to the triangle lattice $NaxCoO_2$, is observed in Cu$_{x}$TiSe$_{2}$. Intercalation of Cu induces a negative MR due to the interaction between conducting carries and localized magnetic moments.
