A cooling system for a rotary electric machine which is provided in a vehicle for driving the vehicle. The cooling system includes: a first pump which is to be mechanically driven accompanying with running of the vehicle, to supply lubricant to the rotary electric machine; and a second pump which is to be driven by a second drive source that is other than a first drive source of the first pump, to supply the lubricant to the rotary electric machine. The first pump is configured to supply the lubricant, through a first passage, to an inside of a rotary shaft of a rotor core of the rotary electric machine. The second pump is configured to supply the lubricant, through a second passage, to a coil of a stator of the rotary electric machine.
