Abstract
A non-combustion suction device includes: a mouthpiece having a suction port; a container configured to accommodate an aerosol source; and a heater including: a porous ceramic substrate that permits infiltration of the aerosol source; a glass layer at least in part on the porous ceramic substrate; a pair of electrode patterns; and a resistor pattern on the glass substrate, the resistor pattern connects the pair of electrode patterns to each other; and a power source connected to the pair of electrode patterns. The power source is configured to supply a power flow through the pair of electrode patterns to cause the resistor pattern to generate heat which atomize, into an aerosol, the aerosol source infiltrated in the porous ceramic substrate; and the porous ceramic substrate has a ratio of porosity to tortuosity of 21 or more.
