The present invention relates to a microwave electric furnace. A microwave supply unit introduces microwave power into an internal space of a furnace body, and the introduced microwave power is raised by a heat generating unit. Heated heat energy is uniformly transferred into a furnace chamber through a heat dissipation unit to which the heat generating unit is fixedly attached, and the outflow of the heat energy heated up in this way is suppressed by a heat insulation unit. With this configuration, the heat energy generated by microwaves can be uniformly transmitted throughout an apparatus and the temperature can be quickly raised to the target temperature.
