Abstract

One of the purposes of the present invention is to provide methods for manufacturing a glass fine particle deposit and a glass base material which enable improvement in the efficiency of adhesion of generated glass fine particles to a starting rod and the glass fine particle deposit. A method for manufacturing a glass fine particle deposit wherein the temperature of at least part of a gas supply pipe (25) from a temperature controlled booth (24) to a clad burner (18) is controlled so as to be higher on the burner side and have a temperature gradient of 5°C/m or more. Preferably the temperature is controlled to have a temperature gradient of 15°C/m or more and more preferably 25°C/m or more. Specifically a tape heater (26) that is a heating element is wound around the outer periphery of the gas supply pipe (25) from the temperature controlled booth (24) to the clad burner (18) and the temperature of the tape heater (26) is controlled thereby achieving management of a predetermined temperature gradient.
