Claim:
A suction filter for a fuel supply apparatus, which is provided in a fuel tank for supplying fuel from the fuel tank to an outside of the fuel tank, wherein the suction filter filters out extraneous material from the fuel to be sucked into a suction port of a fuel pump from the fuel tank, and wherein the suction filter comprises: a core member for forming a fuel passage therein connected to the suction port so that the fuel is supplied from the fuel passage into the suction port; and a filter element sheet for covering the core member and formed in a cup shape, a bottom wall portion of which faces to an inner bottom surface of the fuel tank, wherein the filter element sheet filters out the extraneous material from the fuel flowing from the fuel tank into the fuel passage, wherein the core member comprises: a through-hole formed in a bottom wall portion of the core member, wherein the suction port is inserted into the through-hole so that the suction port is communicated to the fuel passage; and a fuel hole formed in the bottom wall portion at a position adjacent to the suction port so as to pass through the bottom wall portion, so that a space formed in the bottom wall portion is communicated to an outside of the filter element sheet.
