Abstract
A glass particle deposit producing method capable of preventing the variation in the outside diameter of a glass particle deposit and enhancing the yield of a glass raw material is provided. A glass particle deposit is produced by mounting a starting rodand a glass particle generating burnerinside a reaction vessel, introducing a glass raw material into the burner, subjecting the glass raw material to a flame decomposition reaction inside a flame formed by the burnerto generate glass particles, and depositing the generated glass particles on the starting rod. At this time, the dispersion angle of the glass raw material jetted from the burnerwith respect to the center axis of the burneris set to the range of 5 to 70 degrees.
