An infrared emitter that comprises a cladding tube made of quartz glass that surrounds a heating filament as an infrared radiation-emitting element that is connected via current feedthroughs to an electrical connector outside the cladding tube. To improve the service life and power density, the heating filament comprises a carrier plate with a surface made of an electrically insulating material, whereby the surface is covered by a printed conductor made of a material that generates heat when current flows through it.
