An integrated thermal management module may include a first pump for flowing coolant of an indoor heating line for connecting a first heat exchanger heat-exchanged with a condenser of a refrigerant line and an indoor air-conditioning heating core, a second pump for flowing coolant of an indoor cooling line for connecting a second heat exchanger heat-exchanged with an evaporator of a refrigerant line and an indoor air-conditioning cooling core, a fourth pump for flowing coolant of a battery line for connecting a high-voltage battery core and a third radiator, a first valve simultaneously connected to a second radiator line for connecting the first heat exchanger and a second radiator, the indoor heating line, and the battery line to change flow direction of the coolant, and a second valve simultaneously connected to the indoor cooling line and the battery line to change flow direction of the coolant.
