Abstract:
A liquid ejection head is manufactured by covering a mold material arranged on a patterned protecting layer on a substrate and subsequently removing the mold material to produce a flow path. A sacrificial layer employed as the mold material operates as mask for patterning the protecting layer.

Claim (Index 1):
A method of manufacturing a liquid ejection head comprising a substrate having a surface provided with energy generating elements for ejecting liquid and a flow path forming member coupled with the substrate to form a flow path on the surface so as to eject liquid supplied to the flow path by means of energy generated by the energy generating elements, a protecting layer being arranged on a part of the surface exposed to the flow path, the method comprising:\n a protecting layer forming step of forming a protecting layer in a region of the surface including the part thereof exposed to the flow path; a sacrificial layer forming step of forming a sacrificial layer operating as a mold material for the flow path on the protecting layer; a patterning step of patterning the protecting layer, using the sacrificial layer as mask; a sacrificial layer coating step of coating the sacrificial layer with a material for forming the flow path forming member; and a flow path forming step of forming the flow path by removing the sacrificial layer.
