PROBLEM TO BE SOLVED: To provide a glass melting furnace capable of enhancing treating capability without increasing its facility to a large size. SOLUTION: The glass melting furnace comprises a melting furnace body 2 with a melting space 1 therein, and a main electrode 3 provided at a vertically middle part in the melting space 1 with which a glass material to be fed is heated to a molten glass G. The inner end of the main electrode 3 is protruded to a higher position above the upper face of the molten glass G in the melting space 1, forming a protruding part 13. Thus, the melting space 1 above the upper face of the molten glass G also can be heated.
