A printed conductor is applied to a surface to the substrate. The printed conductor is made of an electrically conductive resistor material that generates heat when current flows through it. A process for producing the infrared panel radiator includes: (a) providing the substrate; and (b) applying the printed conductor to a surface of the substrate. To produce an infrared radiator that features homogeneous radiation emission at high radiation power per unit area, the substrate is manufactured from a composite material including an amorphous matrix component and an additional component in the form of a semiconductor material. The printed conductor is provided as a form part with a fixed geometric shape. The printed conductor is applied to the surface of the substrate such that the printed conductor and the substrate are permanently connected to each other. ## Claims ### Claim 1 A method of producing an infrared panel radiator, the method comprising the steps: (a) providing a substrate made of an electrically insulating material;
