Disclosed is an impeller for a turbomachine. The impeller comprises a hub, full blades equidistantly disposed on the hub in a circumferential direction, and a splitter blade disposed between each adjacent two of the full blades. The splitter blade is shaped in such a way that a spanwise distribution of a pitchwise position of a leading edge of the splitter blade is determined according to a spanwise and pitchwise non-uniformity distribution of fluid velocity of a fluid flowing into the splitter blade, whereby a non-dimensional circumferential position of a leading edge of the splitter blade varies in a spanwise direction.
