An aerosol provision system for generating an aerosol from a source liquid,theaerosol provision system comprising: a reservoir of source liquid； a planarvaporisercomprising a planar heating element, wherein the vaporiser is configured todraw sourceliquid from the reservoir to the vicinity of a vaporising surface of thevaporiser throughcapillary action； and an induction heater coil operable to induce current flowin the heatingelement to inductively heat the heating element and so vaporise a portion ofthe sourceliquid in the vicinity of the vaporising surface of the vaporiser. In someexample the vaporiserfurther comprises a porous wadding / wicking material, e.g. an electricallynon-conductingfibrous material at least partially surrounding the planar heating element(susceptor) and incontact with source liquid from the reservoir to provide, or at leastcontribute to, the functionof drawing source liquid from the reservoir to the vicinity of the vaporisingsurface of thevaporiser. In some examples the planar heating element (susceptor) may itselfcomprise aporous material so as to provide, or at least contribute to, the function ofdrawing sourceliquid from the reservoir to the vicinity of the vaporising surface of thevaporiser.
