1. An electronic vaping device comprising:
- a liquid supply region including a liquid material;
an integral heater-wick element in fluidic communication with the liquid supply region, the integral heater-wick element including a heatable portion and at least one wicking portion formed of at least two layers of electrically resistive mesh material, the at least one wicking portion extending into the liquid supply region;
at least one connection structure wrapped around the integral heater-wick element; and
at least one electrical lead connected to the at least one connection structure.
