The right-handed charged current gauge boson $W_R$ can affect significantly on the determination of the $CP$ violation angles to be measured at $B$ factories if the right-handed current quark mixing matrix $V^R$ is taken to a specific form to satisfy the bounds by neutral $K$ meson systems. The $W_R$ contribution can be sizable in $B^0$-$\overline{B^0}$ mixing and tree level $b$ quark decay. The deviation of $CP$ angles in unitarity triangle from the standard model values can be as large as $-37^\circ$ or $ +22^\circ$ for $\phi_3$ ($\gamma$), and $66^\circ \sim 115^\circ$ for $\phi_1$ ($\beta$) and $\phi_2$ ($\alpha$).
