The invention relates to an electronic atomization device which comprises a body and an atomization element. The body is provided with liquid storage cavities and an air suction channel; the atomization element comprises a porous body and a heating structure, the porous body comprises liquid suction faces, an atomization face and side faces, the liquid suction faces are used for sucking tobacco liquid from the liquid storage cavities, and the heating structure is located on the atomization face; an airflow channel is formed in the porous body, flows through the atomization face and is communicated with the air suction channel, and at least one section of the airflow channel extends to the interior of the porous body from the side face. Through the airflow channel section, on one hand, the sectional area of a heat transmission route from the atomization face to the liquid suction faces can be decreased, on the other hand, a large amount of heat transmitted from the atomization face to the liquid suction faces can be brought away, therefore, the heat transmitted from the atomization face to the liquid suction faces can be greatly reduced, the liquid guiding effect of the porous body is improved, and meanwhile energy waste can be avoided. Meanwhile, due to the fact that airflow can generate negative pressure, transmission of the tobacco liquid can be further sped up through the negative pressure.
