1. An atomizer comprising:

  • an oscillator generating surface acoustic waves;

    a porous thin plate having a number of through holes being arranged on the oscillating surface of said oscillator with a small clearance space between said oscillator and said porous thin plate; and

    means for supplying a liquid into said small clearance space between said oscillator and said porous thin plate, andmeans for atomizing the liquid in said small clearance space by surface acoustic wave vibration propagated by said oscillator and spraying the same through the through holes of said porous thin plate.
