Provided is a vehicular coolant control valve configured so that the opened state thereof can be switched over between a state allowing a normal amount of fluid to pass therethrough and a state allowing an amount of fluid less than the normal amount to pass therethrough. The control valve includes a valve body having a magnetic body and controlling flow of the fluid, a valve seat constituting a flow channel for the fluid and coming into contact with the valve body to close the flow channel, a solenoid magnetically maintaining a contact state between the valve body and the valve seat, and an urging mechanism urging the valve body in a direction opposite to a flow direction of the fluid. The valve body includes a first valve body maintaining a contact state with the valve seat when the solenoid is excited and a second valve body capable of allowing passage of a small amount of the fluid when the first valve body is in contact with the valve seat.
