A vehicle component mounting arrangement comprises a vehicle body member, a motor, an inverter and an air conditioning compressor. The motor serves as a drive source. The motor has a motor housing that is elastically supported with respect to the vehicle body member inside a motor room. The inverter is electrically connected to the motor to supply a drive current to the motor. The inverter is vertically arranged above the motor inside the motor room such that a vertical space exists directly between the inverter and the motor in a vertical direction of the vehicle. The air conditioning compressor serves to compress a refrigerant. The air conditioning compressor is attached to the motor housing, and is arranged inside the vertical space between the inverter and the motor.
