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(2ϕ1), where ϕ1 is one of angles of the CKM triangle. The preliminary result is sin(2ϕ1) = 0.45+0.43 ± 0.07-0.44 ± 0.08.
