Abstract

The present invention discloses an ultrasonic atomization piece, a manufacturing method thereof, an ultrasonic atomizer and electronic cigarette. The ultrasonic atomization piece comprises a ceramic substrate, which is provided with an upper silver layer on the upper surface and with a lower silver layer on the lower surface. The ceramic substrate, the upper silver layer and the lower silver layer form piezoelectric ceramic, and glass glaze for protecting the upper silver layer is provided on the upper surface of the piezoelectric ceramic; and a tobacco tar adsorption layer is provided on the upper surface of the glass glaze to form a piezoelectric ceramic component, and the tobacco tar adsorption layer is used for adsorbing, guiding and transferring tobacco tar. In the present invention, as the tobacco tar adsorption layer and the ultrasonic atomization piece body are integrated together, the contact between the ultrasonic atomization piece and tobacco tar is better in an electronic cigarette assembly process, and thus the atomization effect is improved.
