Ceramic atomizing core and electronic cigarette atomizer

The utility model provides a ceramic atomizing core which comprises a porous ceramic base body, a porous transition layer and a conductive heating layer, the porous ceramic base body and the porous transition layer are both of a porous structure, the porous transition layer is arranged on the surface of the porous ceramic base body, and the conductive heating layer is arranged on the porous transition layer. The conductive heating layer is arranged on the surface of one side, far away from the porous ceramic matrix, of the porous transition layer, and the porous transition layer is clamped between the porous ceramic matrix and the conductive heating layer; and the heat conductivity coefficient of the porous transition layer is greater than that of the porous ceramic matrix. The ceramic atomizing core provided by the utility model is not only good in heating uniformity, but also high in atomizing efficiency and large in average atomizing quantity (TPM). The utility model further provides an electronic cigarett
