Electron transport in tokamaks has many different features which are brieflyreviewed. The paper is focused on electron heat transport in conventionaltokamak plasmas. An inter-machine comparison indicates that thenon-dimensional gradient length of the electron temperature profilesR/LTe is almost independent of the devices and varies little withplasma parameters. This strongly suggests that electron heat transport isgoverned by turbulence with a threshold in R/LTe. This is confirmedby modulation experiments using electron cyclotron heating. Simulations withempirical and physics-based transport models confirm this assumption.
