According to the invention disclosed in Japanese Patent No. 588, it is possible to reduce the number of spot welds at the portion where the heater cover side plates 12a and 12b are integrated with the wall of the heating chamber, and to increase the number of spot welds. Although radio wave leakage from the room can be reduced, since the heater cover body 13 is a separate body, the material cost and processing cost of the heater cover body 13 and the processing cost for mounting to the wall of the heating chamber are required. The manufacturing cost is high. On the other hand, it is not objectively easy to automate the process of mounting the heater cover body 13 on the wall of the heating chamber, and the opening of the heating chamber facing the heater cover body 13 is cut off by cutting the wall. There remains a problem that the amount of waste material that can be formed is large.
