Abstract: Provided is a flow control valve which improves a mounting efficiency. An MCV8 includes a housing including a valve-element housing portion, a first communicating aperture which introduces cooling water, which is flown out of a first water channel formed in an engine, to a valve-element housing portion, and a second communicating aperture which discharges the cooling water in the valve-element housing portion to a second water channel formed in the engine; a rotor accommodated in the valve-element housing portion and configured to change a flow rate of the cooling water discharged to the second water channel, according to a rotation angle of the rotor; and a drive mechanism configured to control the rotation angle of the rotor. The first and second communicating apertures open in an engine-side mounting surface of the housing.
