In a fuel pump, a case member and a discharge-side cover define a fuel passage. A holder is held between the case member and the discharge-side cover. Brush terminals are supported by the holder to conduct electricity between power receiving terminals and brushes. The power receiving terminals have connector portions that are connected with the brush terminals. A wall of the discharge-side cover and a wall of the holder clamp the connector portions therebetween. The wall of the discharge-side cover and the wall of the holder partition an installation space, which is isolated from the fuel passage and in which the connector portions are enclosed.
