PROBLEM TO BE SOLVED: To provide a liquid perfume sprayer stably atomizing and spraying liquid perfume by avoiding the liquid perfume leaked from a spray port left around the spray port. SOLUTION: This liquid perfume sprayer is provided with a spray device 30. The liquid perfume is fed from a liquid perfume storage tank to a pressure chamber 32-2 via a liquid inlet 31-1, a liquid feed passage 31-2, a liquid feed hole 31-3, and a liquid guide hole 32-1. A piezoelectric body 32-4 is so driven as to reduce the volume of the pressure chamber 32-2. The liquid perfume is thus sprayed to an outside space via the liquid outlet 32-3 and a spray port 31-4a in the tip of a spray nozzle 31-4. The surface (a surface spray port is formed thereon) formed with the spray port 31-4a is inclined from the horizontal surface by an angleαlarger than a fall angle. The droplet of the liquid perfume stuck to the circumference of the spray port 31-4a falls along the spray port formed surface so that no liquid perfume stuck to the circumference of the spray port is left.
