Claim 4:
5. An electronic vaping device comprising:
a housing extending in a longitudinal direction;
a reservoir in the housing, the reservoir including,
a storage medium configured to store a pre-vapor formulation, the storage medium including a fibrous material, the fibrous material including a plurality of fibers, the plurality of fibers including fibers having diameters ranging from 6 μm to 15 μm;

a vaporizer in the housing, the vaporizer including,
a heating element formed of a conductive material, and
a coating of a porous material adhered to two or more surfaces of the heating element using an adhesive, the porous material including cellulose, the porous material having a porosity of at least 90%, the two or more surfaces including a first surface and a second surface, the coating having a first thickness on the first surface and a second thickness on the second surface, the second thickness being different from the first thickness, the vaporizer being U-shaped, the U-shape having a central portion and side portions;

an absorbent material disposed between the reservoir and the vaporizer and having the same material composition as the coating of the porous material, the absorbent material configured to convey the pre-vapor formulation from the storage medium to the coating of the vaporizer, the absorbent material directly contacting the central portion of the vaporizer, and the side portions of the vaporizer extending away from the absorbent material; and
a power supply in the housing, the power supply electrically connectable to the heating element.
