Beschreibung
Zusammenfassung:	This invention relates to carbon nanofiber having a skin-core structure containing pitch and polyacrylonitrile, to a method of producing the carbon nanofiber, and to a product including the carbon nanofiber. The carbon nanofiber includes polyacrylonitrile and pitch having different properties respectively constituting a skin layer and/or a core layer, with a diameter of 1 μm or less, and thus functions of the carbon nanofiber vary depending on change in composition thereof.
