Abstract ： Electron temperature profiles, the normalized temperature gradient length and the electron heat diffusivity calculated by the heat pulse transfer method in the plasma confinement region, are investigated during electron cyclotron resonance heating (ECRH) in an HL-1M tokamak. The electron temperature profiles keep almost to be constant. The normalized temperature gradient length is in the range of 7-13. Electron heat diffusivity in the ECRH plasmas is larger than that in the ohmically heated plasmas. Electron heat diffusivity during off-axis (ρ < 0.3) ECRH discharge is similar to that during on-axis ECRH discharge.
