The disclosure relates to a thermal mass flow meter for determining a material flow through a vessel. In this case, a heating element is mounted on a holder which is immersed into a vessel with a flowing medium. It is suggested that the holder is subdivided into two zones of differing thermal conductivity, the holder substantially having a high thermal conductivity adjoined by a short zone of low thermal conductivity in which the heating element is arranged.
