Abstract: An ultrasonic atomization piece and manufacturing process thereof relate to the technical field of ultrasonic atomization. The piece comprises a piezoelectric ceramic sheet and at least one composite plate. The composite plate is fixed on one side of the piezoelectric ceramic sheet and includes a substrate and a conductive layer, the conductive layer is in contact with the piezoelectric ceramic sheet, the substrate is provided with atomizing apertures, and the substrate is a polymer film. Compared with the traditional stainless steel thin sheet, the polymer film is used as the substrate material; the force for the piezoelectric ceramic sheet to generate deformation requires being lower, so the piezoelectric ceramic sheet can pull the polymer film to generate deformation with less energy. The difficulty of drilling apertures is reduced, and metal residues splashing will not occur, thereby eliminating the adverse effect of metal residues on the passage efficiency of liquid.
