PROBLEM TO BE SOLVED: To provide a method of manufacturing quartz glass powder for manufacturing a high heat resistant quartz glass body having a high temperature viscosity characteristic equal to or above that of natural quartz glass, high heat resistant quartz glass powder and a high heat resistant quartz glass body easily obtained by the method of manufacturing the high heat resistant quartz glass powder. SOLUTION: The high heat resistant quartz glass powder is obtained by coexisting OH group-containing quartz glass powder and an organic silicon compound to react with each other to remove OH group which is a low viscosity factor in the quartz glass powder and to produce bonded species which is a high viscosity factor by the reaction effect.
