A plurality of metal sectors separately arranged so as to form a bottom of a glass melting furnace. The metal sectors include an upper surface made from a bottom surface of the glass melting furnace, a lower surface opposite to the upper surface, and a plurality of lateral surfaces coming in contact with the upper surface and the lower surface. An electrical arc suppression structure is provided at a part or an entire part of a corner in which the upper surface or the lower surface comes in contact with each lateral surface. The electrical arc suppression structure is a rounded corner or an insulation coating layer. The electrical arc suppression structure enables stable operation of the glass melting furnace.
