To provide a carbon nanotube ink composition that disperses carbon nanotube easily, has excellent storage stability of the dispersed carbon nanotube, and moreover, excels in conformity to a printer (wettability to the printer, filling property in the printer, and sprayability at a constant discharge from the printer).

This carbon nanotube ink composition includes the carbon nanotube, a solvent, and glycol ether. The glycol ether and solvent disperse the carbon nanotube easily, and store the dispersed carbon nanotube stably.
