Abstract: This invention relates to a manufacturing method of a liquid discharge head comprising: forming an active energy ray-curable resin layer on a surface of a substrate on which discharge energy generating elements are formed, attaching a material permeable to active energy rays onto a surface of the active energy ray-curable resin layer, pressing against the material permeable to active energy rays, a master mold being transparent to the active energy rays and having protrusions corresponding to a pattern of discharge ports so as to transfer the protrusions to the material permeable to active energy rays, selectively irradiating the active energy ray-curable resin layer with active energy rays according to a pattern of liquid flow paths so as to cure the active energy ray-curable resin layer, removing the master mold, and removing uncured portions of the active energy ray-curable resin layer.

Abstract: A method of manufacturing a liquid discharge head having a flow path communicating with a discharge port for discharging liquid includes in the following order: preparing a substrate with an evenly provided first layer as a flat layer; forming, of the first layer, a pattern of the flow path for forming the flow path, and a member (A) provided outside the pattern via a gap; providing a second layer so as to fill the gap and to cover the pattern and the member (A); forming, of the second layer, a member (B) for forming the discharge port on the pattern; and removing the member (A), providing, at least on the substrate, a third layer so as to hold it in intimate contact with the member (B), and removing the pattern to form the flow path.
