Abstract

Disclosed are an ultrasonic atomization piece, an electronic cigarette atomization core and an electronic cigarette atomizer. The ultrasonic atomization piece includes a piezoelectric ceramic main body; one surface of the piezoelectric ceramic main body is in contact with a positive electrode conducting layer, and the other surface of the piezoelectric ceramic main body is in contact with a negative electrode conducting layer, the negative electrode conducting layer extends to the surface of the piezoelectric ceramic main body on which the positive electrode conducting layer is located along a side edge of the piezoelectric ceramic main body, and a plurality of convex point areas, which cover the edge of the positive electrode conducting layer are provided on an edge of the negative conductive layer. The ultrasonic atomization piece, the electronic cigarette atomization core and the electronic cigarette atomizer have the advantages of simple structure, reliable electrical connection, reliable work, high atomization speed, good smoke taste and long service life.
