PROBLEM TO BE SOLVED: To obtain a melting furnace capable of effectively deterring the accumulation of metal particles and improving melting performance of glass without using a mechanically stirring device for directly stirring molten glass in a glass melting furnace. SOLUTION: In the glass melting furnace which has a melting furnace body in which molten glass is stored, electrodes for heating which are arranged to face each other at sidewalls of the melting furnace body and a discharging hole which is set at the lower part of the melting furnace, a molten glass spouting device equipped with a pressurization chamber which is installed at the inner wall of the melting furnace body and communicates with the inside of the melting furnace body through an opening, a movable wall installed in the pressurization chamber and a driving source for sending vortex rings into molten glass stored in the melting furnace body by pressing the movable wall and spouting molten glass in the pressurization chamber from the opening into the melting furnace body is installed.
