Abstract
An electron emitting source capable of preventing increase in an inter-terminal resistance and a manufacturing method of the electron emitting source. The electron emitting source comprises an electron emitting chip made of rare-earth hexaboride, and a heater constituted by a carbonaceous member for holding and heating the electron emitting chip, wherein an electrically conductive substance is provided in a gap between the electron emitting chip and the heater.
Claims6
An electron emitting source comprising an electron emitting source tip composed of a rare earth hexaboride;
- and a heater composed of a carbonaceous member for holding and heating said electron emitting source tip, characterized in that an electrically conductive substance is provided in a gap between said electron emitting source tip and the heater.
A method of manufacturing an electron emitting source comprising an electron emitting source tip composed of a rare earth hexaboride and a heater composed of a carbonaceous member for holding and heating said electron emitting source tip, the method of manufacturing an electron emitting source being characterized by comprising a step of providing an electrically conductive substance in a gap between said electron emitting source tip and the heater.
