본 발명은 0.005~1㎛의 평균직경, 0.05~10㎛의 평균길이 및 3이상의 종횡비를 가지는 침상 전기전도성 산화주석 미세 입자를 제공한다. 또한, 본 발명은 주석, 규소 및 알칼리 금속 할라이드를 함유하는 출발물질을 700~1200℃에서 연소시키고 연소 생성물에서 가용성 염을 제거함으로 이루어지는 침상 전기전도성 산화주석 미세 입자의 제조방법을 제공한다. The invention provides acicular electroconductive tin oxide fine particles which has a mean diameter of 0.005-1 mu m and a mean length of 0.05-10 mu m and an aspect ratio of 3 or higher. The invention further provides a process for producing the acicular electroconductive tin oxide fine particles, which comprises firing a starting material containing tin, silicon and an alkali metal halide at 700-1200 DEG C and removing soluble salts from the resulting fired product.
