ABSTRACT:
A process for producing an ink jet recording device involves providing a support member having an electro-thermal converting member and a wiring electrically connected to the electro-thermal converting member thereon, forming a first insulating layer on the support member, and forming on the support member a second insulating layer for increasing a protruded height of a bump-shaped electrode, the second insulating layer having a desired thickness. Other steps in the method involve removing part of the first and second insulating layers to expose a portion of the wiring, forming a bump-shaped electrode to a height corresponding to the thickness of the second insulating layer on the exposed portion of the wiring by electroplating, and removing the second insulating layer, resulting in the bump-shaped electrode having a desired height.
