PURPOSE: A bladeless electric fan is provided to improve the linearity of air blown by applying torque to the air as a guide rib is provided inside an inner flow passage and a nozzle unit. CONSTITUTION: A bladeless electric fan(100) comprises a supporting unit(10), an air inhaling unit(30), an internal fluid path, and a nozzle unit(50). The air inhaling unit is supported by the supporting unit and inhales the outside air. The air supplied from the air inhaling unit is moved inside an inner flow passage. The nozzle unit includes a gap portion(56) where the air inside the inner flow passage is discharged to outside. One side of the inner flow passage is closed so that the air flows in one direction inside the inner flow passage. A partitioning wall is formed inside the inner flow passage along the inner flow passage so that a cross sectional area of the inner flow passage becomes smaller along the air flowing direction.
