Abstract: A fuel pump includes a pump part, a motor part, a motor casing, a motor cover, a terminal, and an electric connector part. The terminal is electrically connectable to an external connector for electricity supply. The electric connector part is disposed at an end portion of the motor cover located on the opposite side from a fitted end of the motor cover which is fitted with a housing, and includes a side surface which is slidably in contact with the external connector to determine a fitting position of the electric connector part relative to the external connector, a bottom face from which the terminal rises up, and an opening which is formed on the side surface to communicate between inside and outside of the electric connector part. The bottom face is an inclined surface whose height becomes lower in a direction from generally a center of the motor cover toward the opening.
