The utility model relates to the technical field of electronic atomization, and provides an air heater and an electronic atomization device.The air heater comprises a conductive ceramic heating piece which is provided with a first end portion and a second end portion and is arranged in a layer-by-layer spaced spiral winding mode from inside to outside with the first end portion as the axis. A spiral roundabout airflow channel is formed between every two adjacent layers, the second end is located at the end, located on the outermost layer of the spiral roundabout path, of the conductive ceramic heating piece, and the conductive ceramic heating piece is used for heating air flowing through the airflow channel to form hot air. The conductive ceramic heating sheets which are spirally wound at intervals have larger heating areas, so that air in the spiral roundabout airflow channel can be more fully contacted with the conductive ceramic heating sheets, and the heating efficiency of the air heater can be improved;
