Abstract: The Belle detector at the KEK-B asymmetric $e^{+}e^{-}$ collider has recorded 6.2 fb$^{-1}$ data at the $Υ(4S)$ resonance by July 2000. Using this data sample, several new results on various B meson branching ratio measurements are presented. We also report on the measurement of the Standard Model CP violation parameter $\sin(2ϕ_{1})$, where $ϕ_{1}$ is one of angles of the CKM triangle. The preliminary result is $\sin(2ϕ_{1})$ = $0.45^{+0.43 \pm 0.07}_{-0.44 \pm 0.08}$.
