Abstract

To provide a capacitor capable of utilizing carbon nanotube characteristics effectively to obtain excellent electric or mechanical characteristics, and a method of manufacturing the same. The capacitor is characterized by including two opposing electrodes, at least one of the two electrodes being formed from a coating film of a carbon nanotube structure in which plural carbon nanotubes with functional groups bonded constitute a mesh structure by cross-linking the functional groups through chemical bonding. The method of manufacturing a capacitor includes: a coating step for coating a surface of a base body with a solution that contains plural carbon nanotubes with functional groups bonded; and a cross-linking step for forming a carbon nanotube structure layer in which the functional groups are chemically bonded to one another, thereby causing the carbon nanotubes to cross-link to one another and build a mesh structure.
