To provide an electric charcoal-burning kiln, capable of producing a high quality charcoal safely, surely also simply even by an absolute beginner.

This electric charcoal burning kiln is provided by housing a treated material 1 in a tightly closed container 3, electrically heating in an air-blocked state, controlling the process, time and carbonizing temperature of the carbonization of the treated material accurately so as to be able to operate the carbonizing treatment automatically. The carbonization is performed along with the 4 processes of drying the treated material, performing the thermal decomposition and carbonization, refining and cooling, and by maintaining the inside or vicinity temperature of the treated material in the drying process at approximately 50-100°C for a prescribed time, elevating the temperature up to 100-500°C in the thermal decomposition and carbonizing process and then maintaining at 450-500°C for a prescribed time, elevating the temperature to an objective temperature selected within 500-1,600°C range in the refining process and maintaining the objective temperature for a prescribed time, and forcing the cooling in the cooling process by blowing a cooling gas without containing oxygen into the carbonizing container from the gas-blowing tube 37.
