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 cm-1 and D represents the maximum peak intensity in the range from 1310 to 1350 cm-1 in Raman spectra.
