A cooling system (60; 124) for a rotary electric machine (MG1, MG2) which is provided in a vehicle (10; 120) for driving the vehicle (10; 120). The cooling system (60; 124) includes: a first pump (PI) which is to be mechanically driven accompanying with running of the vehicle (10; 120), to supply lubricant to the rotary electric machine (MG1, MG2); and a second pump (P2) which is to be driven by a second drive source (20; 122) that is other than a first drive source (32) of the first pump (PI), to supply the lubricant to the rotary electric machine (MG1, MG2). The first pump (PI) is configured to supply the lubricant, through a first passage (62), to an inside of a rotary shaft (30) of a rotor core (90) of the rotary electric machine (MG1, MG2). The second pump (P2) is configured to supply the lubricant, through a second passage (64), to a coil (87, 88) of a stator (82) of the rotary electric machine (MG1, MG2).
