Abstract:
The purpose of the present invention is to provide an emitter capable of easily and highly efficiently emitting electrons, an electron gun using same, and an electronic device.
This emitter is provided with a cathode holder, and an acicular substance secured to the cathode holder. An end, to which the acicular substance is secured, of the cathode holder is bent at α (α(°) satisfies 5
