摘要：
A carbon film of the present invention has an elongated needle shape whose radius decreases toward a tip. The shape is, preferably, a shape in which a field concentration coefficient β in the Fowler-Nordheim equation is expressed by h/r where r denotes the radius in an arbitrary position and h denotes height from the arbitrary position to the tip.
