A smoking article is provided in which a flavor-generating medium is heated electrically to release an aerosol for inhalation by a consumer. The smoking article includes a heater having resistive heating elements printed on a flexible substrate. The heater can be manufactured by circuit board mass production techniques, and can be formed to fit inside an article of the same shape and size as a conventional cigarette. Alternatively, the heater comprises an array of heating elements onto which charges of flavor-generating medium are deposited. The heating elements are connected in a manner which allows the temperature increase in the heater to be concentrated in individually selected heating elements, and requires a minimal number of electrical conductors.
