Abstract
An electronic smoking article includes an outer tube extending in a longitudinal direction, an inner tube within the outer tube and including a pair of opposing slots, a liquid supply comprising a liquid material, a coil heater, a wick and a mouth end insert. The coil heater is located in the inner tube. The coil heater is formed of an iron-free, nickel-chromium alloy and has substantially uniformly spaced windings. The wick is surrounded by the coil heater such that the wick delivers liquid material to the coil heater and the coil heater heats the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol in the inner tube.
