A roaster upper electric heater assembly that prevents a phenomenon of oil flying or smoke and maintains a heating area and baking efficiency equivalent to those of an existing lower heat source body. A lower base portion, a baking plate provided on an upper stage of the lower base portion, an electric heater assembly installed separately from the upper portion of the baking plate, and an end extending upward from a side portion of the lower base portion. An electric heater assembly applied to a roaster comprising: a support base supporting the electric heater assembly by being coupled to an end of a support base extending from the electric heater assembly; The upper dome 4 is coupled to the lower dome, the reflector 5 is coupled to the lower part of the upper dome and reflects heat toward the baking plate, and the heat transfer tube lamp 6 is activated by electricity to generate heat. The reflector has a shape that is opened downward, the heat transfer tube lamp is accommodated in the opening, and a predetermined gap for blocking heat is provided between the reflector and the upper dome.
