PROBLEM TO BE SOLVED: To provide a method for producing a tin oxide fine powder having a specific surface area of≥10 m<SP>2</SP>by a simple treatment means. SOLUTION: The method for producing a tin oxide fine powder having a specific surface area of≥10 m<SP>2</SP>includes: mixing a stannous chloride solution with hot water of a gram-equivalent of≥150 times the gram-equivalent of tin contained in the stannous chloride solution in the presence of hydrogen peroxide; then recovering formed precipitate of tin oxide by filtration; and after drying, heat treating the dried precipitate. It is preferable that hot water having a temperature of 45-75°C is used, and the stannous chloride solution is dropped while taking a time of≥30 min, and after adding pure water to the recovered precipitate of tin oxide, the recovered precipitate is calcined.
