A method for manufacturing a recording head including forming a flow-channel side-wall forming layer which contains a photosensitive resin, on a substrate having ejection energy generating elements and wiring thereon; exposing the flow-channel side-wall forming layer to light, and optically determining a flow channel; forming a shape stabilizing layer which contains a photosensitive resin; forming an ejection orifice forming layer which contains a photopolymerization initiator and a negative photosensitive resin; exposing the ejection orifice forming layer to light, and optically determining an ejection orifice; and developing the ejection orifice forming layer, shape stabilizing layer, and flow-channel side-wall forming layer, in the order named. The photosensitive resin 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. |
