The improved white conductive powder comprises white inorganic pigment particles the surfaces of which are coated with an electrically conductive layer of a dual structure consisting of a lower tin dioxide sub-layer and an upper tin dioxide-containing indium oxide sub-layer. To produce the powder, the hydration product of tin is deposited uniformly on the surfaces of white inorganic particles and, subsequently, an overcoat of indium oxide hydrate containing 0.1-20 wt % of tin dioxide is formed, followed by a heat treatment that is conducted at 350°-750° C. in a non-oxidizing atmosphere.
