A method of manufacturing a helical gear, includes a gear cutting process for forming a roughly-processed gear by applying a gear cutting to an outer circumferential surface of a blank, and a tooth surface forming process for forming a tooth surface by pressing a rolling die against a roughly-processed tooth surface of the roughly-processed gear, wherein a length of a portion of the roughly-processed tooth surface, to which a plastic deformation is applied by the rolling die, in a face width direction is formed to be shorter than a length of a face width of the roughly-processed tooth surface.
