1. A multi-wall carbon nanotube characterized in that the value obtained by dividing the volume of a carbon nanotube grown per 1 g of the catalyst expressed by the following formula (1), by the volume of 1 g of the catalyst is over 30, wherein
Vt/c=(Wt×γt)/(Wc×γc)  Formula (1) (in the formula (1), γt=1/ρt, γc=1/ρc, and Wt is the weight of the carbon nanotube which can be grown with the unit catalyst (1 g), and Wc is 1 g which means the weight of the unit catalyst, and ρt is the apparent density of the carbon nanotube, and ρc is the apparent density of the catalyst).
