ABSTRACT:
The method of manufacturing a recording head has a flow path wall forming step of forming flow path walls on a substrate having energy generating elements formed thereon, an imbedded material depositing step of depositing an imbedded material between the flow path walls and on a top of each flow path wall, a flattening step of polishing a top of the deposited imbedded material, until the top of the flow path wall is exposed, and a step of forming an orifice plate on the tops of the polished imbedded material and the exposed flow path wall. In the step of forming the flow path walls, patterning of a close contact property improvement layer is simultaneously performed to improve a close contact property between the flow path wall and the substrate.
