    • PROBLEM TO BE SOLVED: To provide a method for manufacturing a deposited body of a glass fine particle under excellent manufacturing conditions by preventing the degradation of the tip of a burner while cutting down the expense of an inert gas or nitrogen gas to reduce the manufacturing cost of a product. SOLUTION: The method for manufacturing the deposited body 19 of the glass fine particle comprises the steps of: producing a glass fine particle by using the burner 7 provided with: a port P1 arranged in the center for jetting a gaseous glass raw material; ports P2, P4 arranged outside the port P1 for jetting combustible gas; and ports P3, P5 arranged outside the port P1 for jetting a combustion supporting gas; and depositing the produced glass fine particle on a glass rod 11. When the distance between the port for the combustible gas and the adjacent port for the combustion supporting gas (the thickness of a pipe 32b, a pipe 32c or a pipe 32d) is defined as W (mm) and the flow rate of the combustible gas to be jetted from the port for the combustible gas is defined as V (m/second), the flow velocity V of the combustible gas is made to satisfy 0.3≤V/W and kept to the extent that the burner 7 does not reach a red-hot state.
