A fuel supply pump so structured that an electric motor section and a pump section are housed in a tubular casing provided with a pipe for connection with an external hose, and an opening of the casing is enclosed by an end cover integrally provided with a connection pipe and a terminal. The electric motor section comprises a holder made of an insulating material and consisted of a pair of parts divided about its axis, an armature held at both ends of the holder through bearings, field magnets held on the respective holder plates, yokes arranged to cover the gaps between the paired parts, and brush units arranged to be inserted in the respective holder parts. The pump section comprises a rotor mounted to one end of the axis of shaft of the armature, and a pump-housing fixedly arranged to cover the rotor. Both the electric motor section and the pump section are both covered with the casing, and the opening of the casing is covered with the end cover, so that both the sections are assembled together.
