<P>PROBLEM TO BE SOLVED: To provide a pump module capable of stably maintaining a discharge flow rate of a fuel pump while reducing the size by adopting a fuel filter obtained by combining a suction filter with a high-pressure filter. Ž<P>SOLUTION: A discharge passage 24 communicated with a discharge port 28 is provided, and the outflow direction of fuel flowing out from the discharge passage 24, which is a passage where surplus fuel discharged from a pressure regulator 60 flows, is set in the direction parallel with a rotor axis C and opposite to the fuel filter 40. Thus, the surplus fuel discharged from the pressure regulator 60 is not made to directly flow toward the fuel filter 40, and the route length to the fuel filter 40 is drastically elongated compared to a conventional pump module, so as to achieve easy separation of air bubbles included in the surplus fuel. As a result, this prevents a problem wherein the air bubbles in the surplus fuel discharged from the pressure regulator 60 are sucked in the fuel pump to make a net fuel flow rate discharged from the fuel pump unstable.
