A functional device which is composed of a nanometer-sized functional
structure, which can reduce connection resistance in connecting the
functional structure to an external electrode, and which includes a
wiring section capable of minimizing constraints given to structural
designs of various functional structures, and a method of manufacturing
it are provided. A functional device in which a functional structure
having contained sections in positions spaced from each other is retained
by a carbon nanotube. A gap is formed in the carbon nanotube, and the
carbon nanotube is segmented into a first carbon nanotube and a second
carbon nanotube by the gap. One of the contained sections is contained in
the first carbon nanotube at an opening of the first carbon nanotube
facing the gap, and the other of the contained sections is contained in
the second carbon nanotube at an opening of the second carbon nanotube
facing the gap.
