AI summary

Provided in the embodiments of the present application are an aerosol generating medium and an aerosol generating device. The aerosol generating medium comprises a medium peripheral wall used for being heated to generate aerosol, a hollow space being defined by the medium peripheral wall, and the thickness of the medium peripheral wall being 0.1 mm-0.4 mm. In the aerosol generating medium provided by the embodiment of the present application, the hollow space is defined by the medium peripheral wall, thus reducing the weight and the thickness of the aerosol generating medium, and facilitating heated atomization; after being generated, aerosol can be directly released from the hollow space, thus achieving enough aerosol release space; and the configuration of the thickness dimension of the medium peripheral wall ensures the structural stability of the aerosol generating medium itself, and also allows both the surface and the inside of the medium peripheral wall to be fully heated when the medium peripheral wall is being heated, thus helping to generate aerosol rapidly, and achieving high use experience of users.
