1. A vapor provision system comprising:
a vapor generation chamber;
a reservoir containing a liquid;
a vaporizer located in the vapor generation chamber; and
a liquid transport element arranged to transport the liquid from the reservoir through an opening in a wall of the vapor generation chamber to the vaporizer, wherein the liquid transport element in the vapor generation chamber has a cross-sectional area which is greater than a cross-sectional area of the opening, and wherein a surface of the liquid transport element in the vapor generation chamber is parallel to and abuts a surface of the wall surrounding the opening to help prevent leakage, and wherein the liquid transport element extends into the opening and the liquid transport element in the vapor generation chamber comprises an outwardly flared portion which abuts the wall surrounding the opening.
