Abstract:
1. A method for manufacturing a recording head comprising the steps of: (1) forming a flow-channel side-wall forming layer which contains a photosensitive resin, on a substrate that has ejection energy generating elements and wiring thereon; (2) exposing the flow-channel side-wall forming layer to light, and optically determining a flow channel; (3) forming a shape stabilizing layer which contains a photosensitive resin, on the flow-channel side-wall forming layer; (4) forming an ejection orifice forming layer which contains a photopolymerization initiator and a negative photosensitive resin, on the shape stabilizing layer; (5) exposing the ejection orifice forming layer to light, and optically determining an ejection orifice; and (6) developing the ejection orifice forming layer, the shape stabilizing layer, and the flow-channel side-wall forming layer, in the order of the steps (1) to (6), wherein the photosensitive resin which is contained in the shape stabilizing layer is a material to be cured by a component that is produced upon the exposure of the ejection orifice forming layer and derives from the photopolymerization initiator.
