Electric power steering apparatus

An electric power steering apparatus comprising:

• an electric motor for applying steering assisting torque to a steering system of a vehicle;
• a controller for controlling drive of the electric motor;
• and
• a fixing base as a composing element of the electric motor for fixing the electric motor and the controller thereto, wherein
• the fixing base includes two or more motor bus bars for transmitting a motor drive current to the respective motor coils of the electric motor,
• the connecting terminal portions of the respective motor bus bars are projected from the fixing base,
• the respective motor coils of the electric motor fixed to the fixing base are connected to the motor bus bars, and
• the respective power line bus bars of the controller fixed to the fixing base for transmitting the drive current are electrically connected to the connecting terminal portions of the motor bus bars.
