Abstract

A vapor provision device including a vaporizer for generating a vapor from a vapor precursor material for inhalation by a user; wherein the device has a length L along a length direction, a thickness T along a thickness direction which is orthogonal to the length direction, and a width W along a width direction which is perpendicular to both the length direction and the thickness direction, wherein the width W and length L are both at least twice the thickness T, and wherein a minimum radius of curvature for a peripheral edge of the device in a plane perpendicular to the thickness direction is at least 0.1 W.
