CARBON NANOTUBE, CARBON NANOTUBE DISPERSION, AND USE THEREOF

An electrode membrane having high adhesiveness and electrical conductivity can be produced using carbon nanotubes each of which meets the following requirements (1) and (2). (1) A peak appears at a diffraction angle 2θ=25°±2° in powder X-ray diffraction analysis, and the half value width of the peak is 2° or more and less than 3°. (2) The G/D ratio is 1.5 to 5.0, wherein G represents the maximum peak intensity in the range from 1560 to 1600 cmand D represents the maximum peak intensity in the range from 1310 to 1350 cmin Raman spectra.
