An aggregate of carbon nanotubes having high conductivity and high dispersibility and a method for producing the same are provided. When observed with an electron microscope, the number of layers of 50 or more in 100 carbon nanotubes is 2 to 5 layers, the inner diameter is 3 to 6 nm, and the length of 50 or more in 100 carbon nanotubes. An aggregate of carbon nanotubes comprising carbon nanotubes, wherein 0.2 to 2 μm, 50 or more have two or more bending points between one. The manufacturing method is characterized by comprising carbon nanotubes mainly composed of 2 to 5 layers, having an inner diameter of 3 nm to 6 nm and having a plurality of bending points, and cutting and dispersing the obtained carbon nanotubes.
