Image forming apparatus, liquid-jet head, and method for manufacturing the liquid-jet head

摘要

A liquid-jet head includes a thin film member having a thin part and a thick part, and at least a part of the thin film member is formed of an electroformed film. In the liquid-jet head, the thin film member includes a metallic film forming the thin part, a first electroformed film formed on the metallic film, the first electroformed film forming the thick part, and a second electroformed film covering a connecting part between the metallic film and the first electroformed film.

主权项

1. A liquid-jet head comprising:
a thin film member having a thin part and a thick part, at least a part of the thin film member being formed of an electroformed film, wherein the thin film member includes
a metallic film forming the thin part,a first electroformed film formed on the metallic film, the first electroformed film forming the thick part, anda second electroformed film formed on a top surface of the first electroformed film and on the thin part, wherein the second electro formed film coats a lateral face of the thick part and coats a surface of the thin part, and the second electroformed film is continuously formed between the lateral face of the thick part and the surface of the thin part, to coat an intersection between the surface of the thin part and the lateral face of the thick part, the lateral face extending along a thickness direction of the thick part of the thin film member, and wherein each of the lateral face of the thick part and the surface of the thin part is interposed between the second electroformed film and the first electroformed film.
