The glass supply tubes each include a tube body, a flange portion, which is arranged in an outer circumferential portion of the tube body and has first and second parts, an electrode portion arranged in the first part, and a temperature difference setting portion configured to cause a temperature difference between the first and second parts. The temperature difference setting portion sets a temperature of the first part to be higher than that of the second part.
