A method for manufacturing a liquid discharge head including an energy generating element, which generates energy utilized for discharging a liquid, and a discharge portion provided at a position facing the energy generating element and having a discharge port for discharging the liquid is provided. This method includes the steps of forming a negative photosensitive resin layer used for a member that forms the discharge port on the substrate, and exposing the layer to an i-line to form the discharge portion that is tapered in a direction from the substrate to the discharge port, wherein the layer has an absorbance per 1 μm thickness of about 0.02 to about 0.07 for light used for the exposure.
