An electron-emitting source includes a substrate (11) and a coating film. The substrate is made of a material containing a metal serving as a growth nucleus for nanotube fibers as a main component, and has a plurality of through holes (13). The coating film (12) is constituted by nanotube fibers formed on a surface of the substrate and wall surfaces (14) of the through holes (13). A method of manufacturing an electron-emitting source is also disclosed. <IMAGE> <IMAGE>
