PROBLEM TO BE SOLVED: To provide a glass 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. SOLUTION: In the glass melting furnace which has a melting furnace body 2 in which molten glass G is stored, electrodes 20 for heating which are arranged to face each other at sidewalls of the melting furnace body and a discharging hole 10 which is set at the lower part of the melting furnace, an ultrasonic oscillator which is installed at the inner wall of the melting furnace body and oscillates ultrasonic waves toward stored molten glass is provided.
