| 1. A field emission clement, comprising:
an elongated solid body;
a carbon nanotube yarn wrapping round the elongated solid body;
an electrically conductive adhesive agent applied between the elongated solid body and the carbon nanotube yarn, the electrically
conductive adhesive agent being configured for fixing the carbon nanotube yarn to the elongated solid body, wherein substantially
all of the carbon nanotube yarn is entirely adhered on a peripheral surface of the elongated solid body by the adhesive agent.
