Abstract
A heating device is formed from an electrically conducting, flexible resistance material of carbon fibers arranged between at least two electrodes provided for electrical contacting. The carbon fibers are stretch-broken carbon fiber yarns with a titer of 30 tex to 800 tex and a resistivity of 100 to 600 Ω/m.
