The atomizing core comprises a porous substrate, a heating layer and an electrode; at least one side surface of the porous substrate is provided with an atomizing surface; and by forming an electrode on the porous substrate by using a thick film means, the heating layer is covered on the atomizing surface of the porous substrate, and an electrode does not need to be provided on the heating layer. Therefore, the electrode may be firmly bonded to the porous substrate, and the electrode will also not be impacted by a matrix fluid formed by a high-temperature and high-speed aerosol, so that the electrode does not easily fall off. The method for machining an atomizing core provided in the present invention comprises : first forming an electrode on a porous substrate by using a thick film means; then plating a layer of titanium film on an atomizing surface of the porous substrate by means of a magnetron sputtering process; and then plating a heating layer on the titanium film by means of the magnetron sputtering process, so that the electrode may be firmly bonded to the porous substrate, preventing the electrode from falling off due to the impact of a matrix fluid formed by a high-temperature and high-speed aerosol.
