PROBLEM TO BE SOLVED: To provide white conductive inorganic powder, with a conductive tin oxide layer on the surface of a carrier such as titanium oxide, which does not include a harmful component such as antimony, and consequently, hardly causes environmental contamination and has excellent conductivity and is easy to manufacture, and to provide a manufacturing method thereof. SOLUTION: In the manufacturing method for the white conductive inorganic powder and a manufacturing method thereof, white inorganic powder with a surface layer of stannic hydroxide is used on the powder surface, the stannic hydroxide is reduced in a liquid by making stannous ions come in contact with the stannic hydroxide on the surface of the white inorganic powder, and a surface layer of the conductive tin oxide is formed by excluding oxygen and heating the white inorganic powder collected by separating solid and liquid under an inert gas environment and existence of soluble vapor of stannous salt.
