A fluid discharge apparatus includes a storage chamber, a pressure chamber, a moving body, and a pressure changing mechanism. The storage chamber stores a fluid. The pressure chamber is in communication with the storage chamber through a communication opening, and includes a discharge port to discharge the fluid. The moving body moves inside the storage chamber toward the communication opening, raises a pressure of the fluid in the pressure chamber, and discharges the fluid through the discharge port. The pressure changing mechanism is provided so as to face the pressure chamber, and changes a pressure of the pressure chamber. The pressure changing mechanism actuates in a direction to reduce the pressure chamber pressure after the moving body has started to move toward the communication opening.
