Abstract

An aerosol generating substrate (10) and an aerosol generating product. The aerosol generating substrate (10) is provided with channels (10a); the channels (10a) pass through at least one end of the aerosol generating substrate (10) in the length direction; micropores (10d) are formed in the aerosol generating substrate (10); the micropores (10d) are communicated with the channels (10a). The channels (10a) of the aerosol generating substrate (10) can increase the surface area of the aerosol generating substrate (10), thereby facilitating heat transfer and improving heating efficiency. The aerosol generating substrate (10) releases an aerosol when heated, the aerosol is collected into the channels (10a) by means of the micropores (10d) and is conveyed to a vaping end under the action of vaping negative pressure, and the channels (10a) can reduce the vaping resistance of users during vaping, thereby improving user experience.
