Abstract
A discharge head includes a discharge driving element; an individual electrode formed on the discharge driving element and having a connecting section; and a wired board having a terminal which is joined to the individual electrode by a conductive brazing material. The connecting section is provided to face the terminal, and a metal, which is hardly sulfurized, is exposed in a facing area, of a surface of the connecting section, facing the terminal. A silver sulfide coating is formed on a surface of the connecting section except for a portion facing the terminal. The silver sulfide coating has a low affinity for the conductive brazing material, which is hardly wetted thereby. Therefore, even when the conductive brazing material leaks, then the conductive brazing material is not retained on the silver sulfide coating, and no influence is exerted on the driving operation of the discharge head.
