The invention relates to a conductive polymer composition with a positive temperature coefficient and containing the following constituents: A: 90-15 wt. % polymer constituent; B: 5-30 wt. % particle-shaped electrically conductive carbon, e.g. carbon black, and C: 5-80 wt. % metallized glass bodies with a higher specific electrical conductivity than that of constituent B and an average particle size that is at least a power of ten greater than that of constituent B, whereby the constituents B and C are dispersed in polymer constituent A.
