Fluid control valve including a valve body and an energizing member. The body is engaged with one end of a rotating shaft and moves along an axial direction of the shaft based on shaft rotation. The body opens and closes a first opening by the outer periphery, and one end comes into contact with and separates from a second opening. The member energizes the body on another end side of the shaft. A portion abutting on the second opening and a flow passage in which a fluid flows are at the one end of the body in the case where the first opening is fully closed. Since a valve-closed position of the body can be secured, and fluid flows in the flow passage, when a low flow rate is controlled, a stable flow rate is secured without closing the second opening which is a suction port in a valve-closed position.
