<HEADING LVL="1">SUMMARY [Object]: The present invention provides a process and a device for producing a quartz glass crucible, which generates a stable ring-like arc and is suitable for the production of an excellent crucible having the large open diameter. [Means to be solved]: In a production process and a device for producing a quartz glass crucible, wherein a quartz powder in a mould is heated to be fused by an arc discharge of the electrodes being positioned at around of a rotational axis of a mould, this invention is characterized by using an electrode structure, in which electrodes neighboring each other are positioned at regular intervals in the ring configuration, to form the stable ring-like arc being generated between the electrodes neighboring each other without generating an continuous arc between electrodes facing each other across a central portion of the ring, and heating and fusing a quarts powder.
