Title: Method of producing fiber, and methods of producing electron-emitting device, electron source, and image display device each using the fiber

Abstract: A method of producing a fiber, comprising the steps of introducing catalytic particles originally formed in a particle-forming chamber into an arraying chamber together with a carrier gas, to cause the catalytic particles to become arranged on a substrate disposed in the arraying chamber. A next step includes growing fibers, each including carbon as a major component, based on the catalytic particles arranged on the substrate. The fibers grow by heating the catalytic particles arranged on the substrate in an atmosphere containing carbon.
