The present disclosure provides a wind turbine blade with an improved trailing edge structure and a manufacturing method thereof. The wind turbine blade includes an upper shell, a lower shell, and a trailing edge, where a trailing edge bonding region enclosed by the upper shell, the lower shell and the trailing edge is filled with composite materials, and the composite materials are discontinuous in an airfoil chordwise direction. The manufacturing method includes the following steps: S1: manufacturing reinforcements with a same cross-sectional shape as the trailing edge filling region for composite materials; and S2: integrally molding the reinforcements, a fiber fabric and the upper shell, providing the lower shell, combining the upper shell and the lower shell, and performing heating for curing and molding. The discontinuous filling structure reduces usages of the adhesive and the reinforcements of the composite materials. The small web can improve a strength of the trailing edge region, and reduce a bonding width of the trailing edge. Therefore, the present disclosure realizes a light weight of the wind turbine blade.
