A cooling system includes a rotary electric machine, a pump that pumps coolant, a first coolant flow path that guides coolant to the rotary electric machine, a second coolant flow path branching off from the first coolant flow path, a pressure regulation valve provided in the second coolant flow path, a first orifice provided at downstream than the pressure regulation valve in the second coolant flow path in coolant flow direction, a third coolant flow path branching off from between the pressure regulation valve and the first orifice in the second coolant flow path and joining to a downstream than the branching position of the second coolant flow path in the first coolant flow path in coolant flow direction, and a switching valve provided in the third coolant flow path and that allows coolant flow to the first coolant flow path when experiencing a pressure of a threshold or more.
