Cable routing structure

A cable routing structure comprising:

• a drive train;
• an electric motor housed within the drive train;
• a power control unit configured to convert electric power of a battery to alternating current and supply the alternating current to the electric motor, the power control unit being fixed to an upper portion of the drive train, and on-board components being arranged on both sides of the power control unit in a lateral direction of a vehicle;
• an electrical component arranged on a side of a plane on which the power control unit is present, the plane including a side surface of the power control unit that faces toward a front or a rear of the vehicle;
• and
• a first cable connecting the power control unit to the electrical component, a first end of the first cable being connected to the side surface of the power control unit, a second end of the first cable being connected to the electrical component, and the first cable being routed through a space defined by the power control unit and the drive train.
