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.
A manufacturing method of a liquid discharge head which comprises discharge ports for discharging a liquid, discharge energy generating elements for discharging the liquid, and liquid flow paths which incorporate the discharge energy generating elements and communicate with the discharge ports, the manufacturing method comprising:
