The electrical resistance hot-plate of the plug of the lighter comprises a holder which houses and retains a heating element in the form of a metal strip shaped, for example, in accordion-pleated folds or a coil, so as to have consecutive turns which together define respective flat faces at the two opposing edges of the strip, at least one of which is so situated in correspondence with an open side of the holder for receiving the tip of a cigarette. The consecutive turns of the strip are spaced apart so as to define a plurality of interstices, and the holder has at least one opening opposite its open side to expose a greater part of the corresponding flat face of the heating element and allow a flow of air from one face of the element to the other.
