PURPOSE: An impeller for a fuel pump is provided to increase the discharge of fuel and the kinetic energy of the fuel by applying force to the fuel impinging with a blade in the direction of matching with the rotating direction of a section revolution of the fuel between blades. CONSTITUTION: An impeller for a fuel pump comprises a body(11), blades(15) and a connection part(19). The body comprises an insertion part into which a rotary shaft is inserted. The blades are radially formed around the body. The blade comprises an inner part(16) making contact with the body and an outer part(17) bent from the inner part. The inner part slopes in the opposite direction to a progressing direction for the straight line passing through the rotation center of the body on each horizontal cross section. The outer part is bent along the progressing direction from the end of the inner part. The connection part connects the blades from outside to the circumference.
