PROBLEM TO BE SOLVED: To provide an electroconductive tin oxide powder which is free from harmful substances such as antimony, highly safe and electroconductive and exhibits excellent transparency and heat ray-shielding ability, when compounded in a transparent resin film. SOLUTION: The electroconductive tin oxide powder has optical characteristics in which a 2-3μm-thick transparent thin film containing 30-80% of the tin oxide has a visible light transmittance of≥80% and an infrared transmittance of≤60%. Preferably, the electroconductive tin oxide powder has a compact volume resistivity of≤10Ωcm and the transparent thin film having the tin oxide content and the thickness as described above has a surface resistivity of≤1×10<SP>10</SP>Ω/sq. In addition, the method for manufacturing the same is provided. COPYRIGHT: (C)2008,JPO&INPIT
