Ink jet print head and manufacturing method thereof

摘要

An ink jet print head and a manufacturing method thereof that is improved so as to simplify a glue layer (40) forming process including a glue layer of the ink jet print head is made of a silicone modified resin having a photosensitive property, such as a silicone modified polyimide resin. The glue layer can be formed by coating a silicone modified polyimide resin solution (40a) on a substrate, forming a silicone modified polyimide resin layer by vaporizing a solvent from the coated silicone modified polyimide resin solution, and patterning the silicone modified polyimide resin layer.
