A flow rate control valve comprises a piezoelectric actuator and a displacement amount-amplifying mechanism for amplifying a displacement amount of the piezoelectric actuator. An amplified displacement amount, which is amplified by the displacement amount-amplifying mechanism, is transmitted to a valve head. The valve head is operated to regulate a flow rate of a fluid passing through a communication passage for making communication between an inflow passage and an outflow passage of a valve body. The displacement amount-amplifying mechanism is provided with an input section and an output section which are displaceable along an axis, and a displacement-transmitting section which is tiltably displaceable by a predetermined angle.
