Abstract

A radiant heating body for a cooking hob has a heating conductor comprising a metal foil and an insulating bottom (12). To make the heating conductor easy to fit and to provide advantageous heat radiation properties the flat geometrical heating conductor pattern is separated out of the metal foil. The pattern forms heating limbs (1) whose large surface is towards the cooking hob and which are held at least at an outer annular rim (13) of the insulating bottom (12).
