A wind power turbine includes a frame, a drag-type fan unit and a lift-type fan unit. The frame has a base, a shaft, an electricity generator and a plurality of air-guiding plates. The air-guiding plates are disposed on the base, and the shaft has one end connected to the electricity generator. The drag-type fan unit has a plurality of drag-type blades coupled to an outer circumference of the shaft. The lift-type fan unit has a plurality of lift-type blades disposed around the drag-type blades. Each of the air-guiding plates has a first side and a second side, and the first and second sides are parallel to the shaft. An air inlet is formed between the first sides of adjacent two of the air-guiding plates, and an air outlet is formed between the second sides of adjacent two of the air-guiding plates. The air inlet is larger than the air outlet.
