Claim 21:
22. A carbon nanotube manufacturing apparatus comprising:
a mist generating unit that generates a mist including a catalyst particle and a liquid carbon source;
a tubular carbon nanotube growing unit that is connected to the mist generating unit and grows a carbon nanotube from the catalyst particle by heating the mist; and
a drawing unit that draws a carbon nanotube that is connected to the tubular carbon nanotube growing unit on a side opposite to a side where the mist generating unit is disposed;
wherein a hollow portion in the drawing unit passing carbon-containing gas has a cross section smaller in area than a hollow portion in the tubular carbon nanotube growing unit passing the carbon-containing gas.
