摘要

A method of producing a discharge device enables an LaB6 cathode (12) to be formed by a thick-film printing method. The method comprises applying to a base electrode (10) a paste prepared by mixing LaB6 powder with alkali glass powder in a proportion of 20 to 40 wt.% with respect to the LaB6 powder, burning the paste, and activating the paste by gas discharge with a large current after an exhaustion step to form the LaB6 cathode (12) on the base electrode (10).
