PROBLEM TO BE SOLVED: To provide processes for preparing conductive tin oxide particles used for a transparent conductive coating material, an antistatic coating material, an infrared-absorbing coating material, an electric conductivity regulator for electrically conductive ceramic, a filler for a pressure membrane paste, and an antistatic or electrically conductive agent, or the like, for paper/fiber/plastic rubber; an aqueous composite tin oxide-antimony oxide sol; an aqueous conductive tin oxide sol; and an organic conductive tin oxide sol. SOLUTION: Composite tin oxide-antimony oxide particles contain an SnO<SB>2</SB>component derived from a tin oxide sol and an Sb<SB>2</SB>O<SB>5</SB>component derived from an antimony pentoxide sol in a weight ratio Sb<SB>2</SB>O<SB>5</SB>/SnO<SB>2</SB>of 0.02-0.2. The process for preparing the conductive tin oxide particles comprises steps wherein a sol comprising the composite tin oxide-antimony oxide particles is dried, baked at 400-800°C and pulverized.
