The invention relates to a blade for the fan of a jet engine. The leading edge of the blade has a sweep angle greater than or equal to +28° in a part of the blade that is situated at a radial height of between 60% and 90% of the total radial height of the blade as measured from its root to its tip, and the difference (delta1) in sweep angle of the leading edge is less than 10° between a radial height of minimum sweep (Hmin) corresponding to a minimum sweep situated in that part of the blade of between 20% and 90% of the radial height of the blade, and a radial height (Hmin+10) measured at 10% above this radial height of minimum sweep.
