A thermal management system includes: a first flow path, a second flow path, a third flow path, and a fourth flow path; an electrical storage device configured to exchange heat with the heat medium in the first flow path; a drive device configured to exchange heat with the heat medium in the second flow path; a radiator located in the third flow path; a chiller device located in the fourth flow path; and a switching device. The switching device is configured to cause a first circuit to be formed when heating for increasing a temperature of the electrical storage device is performed. The first circuit has a first path in which the heat medium circulates through the first flow path and the fourth flow path and a second path in which the heat medium circulates through the second flow path and the third flow path.
