A heating and atomizing aroma diffuser includes a cover with an outlet thereof, an atomization core including a heating member and a liquid conduction member surrounding around the heating member, a spice storage, an airflow generator with an inlet thereof and a control unit. The inlet, the airflow generator, the spice storage, the atomization core and the outlet are connected to cooperatively form an air passageway thereof. The control unit is electrically connected to the heating member and the airflow generator to drive the heating member to generate heat, so that spice liquid adsorbed on a surface of the liquid conduction member is atomized into steam by high temperature, and then simultaneously drive the steam to diffuse into the air through the air passageway, thereby the steam can be diffused rapidly and sufficiently into the air, and has widespread spectrum and strong fragrance.
