The present disclosure relates to a fibrous electrode and a supercapacitor including the same. In the fibrous electrode, a carbon nanotube sheet is spirally wound on a surface of an elastic fiber. Thus, the fibrous electrode may maintain a fiber shape, and an electrical connection structure in the carbon nanotube sheet may not be damaged by deformation of the elastic fiber. That is, the fibrous electrode may be reversibly changed to maintain excellent electrical conductivity. In addition, the fibrous electrode has a fiber shape having a diameter of hundreds of micrometers, and thus the fibrous electrode may be light and may have excellent durability and excellent life span characteristics.
