Abstract
An ITO sintered body according to the present invention has a density thereof of between 90 and 100% and a sintering particle size of between 1 and 20 .mu.m. A proportion of (In.sub.0.6 Sn.sub.0.4).sub.2 O.sub.3 in the ITO sintered body is 10% or below. Such an ITO sintered body is manufactured by mixing an indium oxide powder, whose BET surface area is between 15 and 30 m.sup.2 /g, a BET size/a crystallite size is 2 or below, and an average primary particle size is between 0.03 and 0.1 .mu.m, with tin oxide whose BET surface area is 3 m.sup.2 /g or below, and then by sintering the mixture.
