A carbon nanotube attached member has a substrate, which is mainly made of aluminum, and a aligned CNT film which is aligned along an alignment direction ORD. A carbon nanotube/CNT, which forms the aligned CNT film, has a length of 200 micrometers or longer. The CNT is synthesized starting from a mixed gas of acetylene, hydrogen, and argon. Furthermore, carbon dioxide is added to maintain catalyst activity. A ratio of acetylene:carbon dioxide is adjusted from 1:10 to 1:300. The aligned CNT film is partially formed. The formation range of the aligned CNT film is set by inhibiting synthesis and/or aligned growth of the CNT by a rough surface or a carbon-containing substance.
