Abstract:
1. A composition containing carbon nanotubes which meets all of the following conditions (1) to (4); (1) when observed via transmission electron microscopy, 50 or more of 100 carbon nanotubes are double-walled carbon nanotubes; (2) the carbon nanotubes have an average outer diameter in the range of 1.0 to 3.0 nm; (3) by thermogravimetric analysis under atmosphere at a temperature increase rate of 10° C./minute, a high temperature combustion peak is at 700 to 850° C., and the relationship between low temperature weight loss (TG(L)) and high temperature weight loss (TG(H)) is TG(H)/(TG(L)+TG(H))≧0.75; and (4) the composition containing carbon nanotubes has a volume resistance value of 1.0×10
