Abstract
A fuel filter of the invention is attached to a suction side of a fuel pump. The filter includes a bag member made of a filtration material, a cylindrical portion provided to the bag member to allow the suction side of the fuel pump to communicate with an interior of the bag member, and a shape keeping frame for the bag member extending from the cylindrical portion to an inside of the bag member. The shape keeping frame includes a plate shape portion to make a surface contact with an inner surface of the bag member in front of an opening of the cylindrical portion inside the bag member. Thus, the fuel filter does not impair a suction ability of the fuel pump even if a space between the opening of the cylindrical portion as the suction side of the fuel pump and the inner surface of the bag member opposed thereto is narrow.
